Fast answer: Diamond Color Grades D, E, F: Report Fields, Cut Data, Inscription, and Value is a buyer decision, not just a style choice. Shortlist pieces by real-light appearance, comfort, documentation, budget fit, and service terms.

Inspection points before purchase

Check the grading report, measurements, setting profile, metal color, return terms, warranty, and delivery timing. Two lab-grown diamond pieces with similar photos can feel very different once cut, spread, setting height, and daily-wear comfort are compared side by side.

Questions that prevent regret

Ask whether the piece can be resized, how it should be cleaned, what is covered after delivery, and whether the photos show the actual stone or a representative sample. Clear answers protect the purchase after the excitement of the design wears off.

Choosing a diamond for an engagement ring, three-stone anniversary ring, or diamond anniversary band means navigating color grades that affect both appearance and price. Most buyers discover that the top grades—D, E, and F—command significantly higher prices, yet they struggle to understand why that premium matters for their specific ring design. Is paying extra for a higher color grade actually worth it for a cathedral setting with pave band?

Here's what industry experience teaches: after working with clients selecting their perfect stone for over a decade, I've watched couples agonize over D versus F color, only to hold both stones side-by-side and honestly perceive nothing different when mounted in a 14K white gold solitaire setting. The answer hinges on understanding what technically distinguishes these grades, how they interact with specific settings and precious metals like 950 platinum or 18K white gold, and where informed buyers can optimize their budget without compromising beauty.

A bride recently told me she cried when she first saw her ring—not because of its specs, but because of how it made her feel. "I didn't know the difference between D and F," she said, "but I knew this ring was the one." That moment captures what this guide really aims to help you achieve: confidence in your choice, whether you select the absolute top grade or the practical sweet spot.

The GIA Color Scale: How Diamonds Get Their Whiteness Rating

The Gemological Institute of America (GIA) created the standardized color grading system we use industry-wide, introducing the D-through-Z scale in the 1950s. Before this standardization, jewelers used inconsistent terminology that made comparing diamonds nearly impossible. GIA's approach brought objectivity by establishing standardized criteria for evaluating a diamond's body color under controlled viewing conditions with 6500K color temperature fluorescent lighting.

The scale runs from D (completely colorless) to Z (light yellow or brown). Diamonds graded D through F fall into the "colorless" category on GIA reports, meaning they show no detectable warmth even under 10x magnification by trained graders. G through J are classified as "near colorless" on the certificate, with hints of color that become more apparent in stones over 1.5 carats or under incandescent lighting. K through M show faint color, while N through Z display obvious warmth visible to the unaided eye.

Most commercial diamonds fall into the G-J range. Buyers seeking maximum whiteness often target D, E, or F grades specifically for platinum solitaire settings or three-stone designs. Understanding this GIA scale helps you read certificates accurately and communicate clearly with jewelers about your requirements.

Why D Through F Are Considered Colorless

The distinction matters because it separates premium specifications from practical ones in the market. A D color diamond carries no detectable yellow, brown, or green undertone in the girdle, crown, or pavilion areas when examined by certified graders. An E color shows no warmth to the naked eye under any viewing condition. F delivers the same visual experience in normal lighting conditions in a cathedral setting or bypass shank.

The microscopic differences between D, E, and F exist only in laboratory conditions using standardized color temperature lighting. Under a jeweler's 10x loupe with proper illumination, trained graders can spot trace color differences using master stones for comparison. But in a pavé engagement ring on someone's hand under restaurant lighting or natural daylight? The difference becomes invisible to the naked eye in over 95% of viewing conditions.

D Color Diamonds: Absolute Purity at a Premium

A D color diamond represents complete purity. No traces of yellow, brown, green, or any other undertone exist within the stone's crystal structure. This grade sits at the very top of the GIA color scale, making D color diamonds extraordinarily rare in natural formations. A natural 1.2ct D-VS1 round brilliant with GIA certification commands premium prices because of its scarcity in the earth's mantle.

The exceptional whiteness of D color stones makes them particularly striking in platinum solitaire settings and three-stone anniversary ring designs where the center stone dominates visually. 950 platinum and 14K white gold metals pair optimally with D color diamonds because these cool-toned metals complement the stone's purity without introducing competing warmth that could mask the grade's subtle advantages.

Buyers concerned about investment value often gravitate toward D color grades. While all diamonds depreciate from retail prices upon purchase, higher color grades in the D-F range tend to hold resale value more reliably. A certified D-VS1 from GIA or IGI provides documented top-tier quality that appraisers and insurers recognize universally.

One couple came to us wanting the absolute best for their engagement ring, budget be damned. They selected a 1.5ct D-VVS1 round brilliant in platinum, and when she opened the box at their anniversary dinner, her hands shook. "I never thought I deserved something this beautiful," she whispered. Was it objectively necessary? No. But watching her face made me understand that sometimes the grade isn't about perception—it's about what makes someone feel worthy of celebration.

When D Color Makes Sense

D color becomes worth the premium in specific scenarios. If you're choosing a diamond solitaire that will be examined closely at dinner events and professional settings, the extra whiteness adds measurable prestige in a flush fit or prong setting. In a bezel setting with 950 platinum that creates maximum contrast, D color demonstrates its technical superiority over lower grades. And for buyers who plan to insure the ring for values exceeding $8,000, the documented top grade from GIA provides objective verification for insurance documentation.

Honestly, most couples don't need D color. The perceptual difference between D and F in a 1.5-carat round brilliant set in 14K white gold simply isn't detectable in daily wear. That said, if having the absolute best specifications matters emotionally for milestone moments (and I completely understand this for engagement rings), D delivers that psychological satisfaction with IGI or GIA documentation to prove it.

E and F Color: Near-Perfect Alternatives with Real Savings

An E color diamond appears completely colorless to the naked eye, even when examined by trained gemologists under controlled lighting using 0.75ct+ stones. Only sophisticated instrumentation like spectrophotometers can detect the microscopic color differences separating E from D grades. For all practical purposes in a cathedral setting with three-stone design, E color provides D-like beauty at a meaningfully lower price point ranging from $2,800-$4,200 for a 1ct lab-grown E-VS1.

F color diamonds follow a similar profile. Under normal viewing conditions—whether in a jewelry store under halogens, office lighting with fluorescent tubes, or outdoor daylight at 5000K—F graded stones appear entirely colorless in a pavé band or solitaire mounting. Only side-by-side comparison against higher grades in specialized lighting booth conditions with controlled color temperature might reveal any subtle warmth, and even then, trained graders debate whether visible differences exist.

Both E and F grades represent excellent choices for engagement rings, anniversary bands, or any jewelry where you want the brilliance of a high-quality stone without paying D color premiums. A 1.5ct F-VS2 round brilliant in 14K white gold delivers indistinguishable beauty compared to a 1.5ct D-VS2 at roughly 15-20% lower cost. The savings often allow buyers to upgrade carat weight from 1ct to 1.5ct or improve cut quality from Very Good to Excellent—factors that create more visible impact than the jump from F to D color.

The Price Math That Matters

What most buyers don't realize: the price jump from F to D color often equals $800-$2,500 depending on carat weight and certification level, yet in a prong setting or channel set band, that difference remains invisible to the naked eye in virtually all viewing conditions. Those dollars could instead fund a larger stone (gaining 0.3-0.5 carats), a better cut grade (upgrading from Very Good to Excellent), or a more elaborate setting (adding pavé accents or a split shank).

We've seen clients walk away with a 1.5-carat F color SI1 round brilliant instead of a 1-carat D color VS2—same $5,000 budget, dramatically different visual impact in a cathedral solitaire setting. The bigger, well-cut F color stone outsparkles the smaller D every single time because cut quality (proportions, symmetry, polish) determines light performance more than color grade.

One couple chose a 2ct F color oval in a halo setting after I explained the savings versus D color. Six months later, they sent photos from their proposal at sunset—she said yes through happy tears, and the ring caught the golden light beautifully. "People keep asking about it," he told me later. "No one has asked about the color grade."

Can You Actually See the Difference Between D, E, and F Diamonds?

Scientific studies on color perception consistently reveal that most people cannot distinguish between D, E, and F graded diamonds without controlled conditions and direct comparison. Research conducted by gemological institutions confirms that the human eye struggles to perceive the microscopic color traces separating these grades when stones are viewed independently in normal lighting conditions.

Cut quality dramatically influences how colorless a diamond appears regardless of its actual grade. A well-proportioned 1.2ct excellent-cut round brilliant with ideal crown angles (34-35°) and pavilion depths (40.6-41°) maximizes light return and creates such intense sparkle that any subtle body color becomes effectively invisible to observers. Conversely, a poorly cut stone—even with a D color grade—may appear dull or lifeless because light escapes through the pavilion facets rather than reflecting back to the viewer as brilliance.

Professional gemologists use standardized viewing conditions: 6500K fluorescent overhead lighting, neutral gray background, and comparison stones spaced precisely 4 inches apart to identify subtle grade differences. Consumers shopping in retail environments rarely have access to these controlled conditions, which means the practical visible difference between D, E, and F often amounts to nothing perceptible.

My recommendation after years of hands-on experience: prioritize cut quality above all other factors (aiming for GIA "Excellent" or "Very Good" grades), and consider E or F color grades as the practical sweet spot for value-conscious buyers selecting lab-grown diamonds certified by IGI or GIA.

How Diamond Shape and Setting Affect Perceived Color

Diamond shape plays a crucial role in how color appears in the finished piece. Round brilliant cuts excel at masking body color because their 57-facet arrangement returns maximum white light to the viewer's eye. This is why round stones remain the most forgiving shape for near-colorless grades like G and H in yellow gold settings.

Fancy shapes present different challenges. Princess cuts and cushion cuts often show more body color than rounds of equivalent grades because their square or rectangular outlines allow the eye to perceive more of the stone's interior pavilion. Emerald cuts, with their step-cut faceting creating large table reflections, reveal clarity and color more transparently than brilliant cuts. Buyers choosing emerald or Asscher cuts benefit from targeting E or F color grades to ensure purely colorless appearance in any lighting.

Metal choice significantly impacts perceived color as well. Yellow gold settings in 14K or 18K create a warm environment that masks lower color grades effectively. A 1ct diamond graded H color that appears slightly warm in a white gold four-prong setting looks completely colorless in a yellow gold bezel setting because the surrounding metal tone harmonizes with any subtle warmth in the stone. This knowledge lets savvy buyers allocate budget appropriately—if you love vintage-inspired Yellow Gold Jewelry, you can comfortably choose G or H color grades while saving $1,200-$2,000 for other specifications.

Best Diamond Shapes for Colorless Grades

Round brilliant diamonds remain the top choice for maximizing color grade efficiency in any setting type. The faceting pattern masks body color so effectively that you can often select G or H grades in 14K white gold without visible sacrifice to untrained observers.

Oval and pear shapes offer a middle ground for halo settings. Their curved outlines hide color better than square or rectangular cuts, making E or F grades reliable choices for three-stone anniversary designs. A 1.8ct oval F-VS2 in a halo with pavé band delivers impressive presence with optimal color presentation.

Emerald cuts and Asscher cuts demand more attention to color grade. The step-cut faceting creates mirror-like reflections that highlight any warmth in the stone, especially in 950 platinum settings. We typically recommend E or F color minimum for these shapes.

Halo settings and pavé bands introduce additional complexity for color coordination. The small accent stones (melee) surrounding a center stone should ideally match or complement the center stone's color grade. A D color 1ct center with heavily included or off-color J-color melee stones creates visual inconsistency that undermines the overall appearance, especially under spot lighting in jewelry stores.

Why Lab-Grown Diamonds Offer Exceptional Color Quality

Lab-grown diamond technology has transformed the market for high-color stones. These diamonds are grown using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) processes that replicate the conditions creating natural diamonds deep within the Earth. The result: lab-grown diamonds achieve consistent, exceptional color quality in the D-F range more affordably than their mined counterparts, with typical prices of $2,500-$4,500 for 1ct F-VS1 stones certified by IGI.

Industry analysis predicts continued growth in lab-Grown Engagement Ring purchases, with color quality serving as a major driver for budget-conscious buyers. Because producers can control growth conditions more precisely than nature controls natural formation over billions of years, lab-grown stones consistently reach D-F color ranges without the scarcity premium attached to rare natural diamonds of equivalent grade.

Buyers seeking Sustainable Engagement Rings increasingly choose lab-grown options for anniversary bands and three-stone designs. The environmental footprint of lab-grown production remains substantially lower than traditional mining, and ethical concerns about conflict diamonds disappear entirely when production occurs in certified laboratory environments in the US or Europe.

Lab-Grown vs Natural: Understanding the Color Difference

How are Lab-Grown Diamonds Made? The controlled CVD or HPHT environment allows producers to minimize nitrogen and other trace elements that cause yellowing in natural stones. This means lab-grown diamonds naturally achieve F, E, or D color grades without the premium attached to rare natural formations.

When comparing Lab-Grown Diamonds vs moissanite, the distinction becomes clearer. Moissanite exhibits more fire and rainbow flashes but often shows a gray or yellow tint under certain lighting angles. Lab-grown diamonds provide true colorless appearance without the optical effects that some buyers find distracting in diamond jewelry.

Colored lab-grown diamonds have also gained popularity for fashion jewelry, with options spanning pink, blue, yellow, and green. These fancy colors often command premiums, but colorless options remain the most popular choice for traditional engagement rings and anniversary bands.

The price advantage opens new possibilities for buyers. A 2ct F color lab-grown diamond solitaire that would cost $15,000-$20,000 in mined form becomes accessible at $4,500-$6,500 with IGI certification. This democratization allows couples to prioritize the 4Cs that matter most—larger size, better cut, or higher color—without forcing difficult tradeoffs.

We've watched couples walk in feeling overwhelmed by the sticker shock of mined diamonds, then leave with tears of relief holding a 1.8ct F color stone they never thought they could afford. One groom told me he proposed that same weekend. "She said yes before she even noticed the size," he laughed. "She just saw the sparkle in my eyes when I opened the box."

Celebrity Influence on Lab-Grown Preferences

Celebrity engagement ring announcements featuring lab-grown center stones have driven significant consumer interest in recent years. High-profile proposals normalizes lab-grown choices and reduces social resistance for couples considering these options for cathedral settings or vintage-inspired designs.

Lab-Grown Diamond Certification: What to Look For

Certification provides essential third-party verification of a diamond's quality. For lab-grown stones, the International Gemological Institute (IGI), GIA, and GCAL (Gem Certification and Assurance Lab) all offer grading reports specifically designed for laboratory-produced diamonds. These certificates confirm color, clarity, cut, and carat weight using the same standardized criteria applied to natural diamonds.

When reviewing a grading report, locate the color grade clearly stated near the top of the document. The report should identify whether the stone is natural or lab-grown, as this distinction significantly affects Value and Resale considerations. Look for the specific letter grade—D, E, or F—rather than vague descriptors like "colorless." Check the report number against the laser inscription typically found on the girdle of certified stones.

Reputable sellers provide certification for every stone they sell. Watch out for vendors offering diamonds without documentation or using in-house "certification" that lacks independent verification from GIA, IGI, or GCAL. Missing documentation represents a significant red flag that should prompt you to seek purchases elsewhere.

Request the certificate before purchasing and take time to understand its contents. The report will show the plotting diagram, clarity characteristics, dimensions in millimeters, and proportion grades for polish and symmetry.

Practical Tips: Choosing the Right Color Grade for Your Budget

Smart diamond buying requires balancing the 4Cs against each other and against your personal priorities. Cut quality deserves your highest consideration because poor cut undermines brilliance regardless of color, clarity, or carat weight. A diamond's cut determines how effectively it returns light, creating the sparkle that makes pavé engagement rings memorable and photographable.

For round brilliant diamonds in platinum or white gold settings, we typically recommend targeting F or G color grades as the practical sweet spot for lab-grown stones priced under $5,000. These stones appear completely colorless against 14K white gold or 950 platinum while costing 15-25% less than D or E grades. The visible difference remains imperceptible under normal viewing conditions in a cathedral setting.

Consider your lifestyle when selecting color grades. Someone who wears their ring constantly—working with hands, exercising, gardening—may want to prioritize durability and lower maintenance over premium color grades, perhaps selecting a bezel setting that protects the stone's girdle from impact. Conversely, someone who removes their ring for activities and stores it in a jewelry box might prioritize maximum specifications for special occasions.

Matching Wedding Bands and engagement rings deserves separate consideration. If your anniversary band or wedding band will sit next to your engagement ring daily in a flush-fit or shared-prong design, the two pieces should complement each other visually. An F color engagement stone beside an H color anniversary band creates jarring contrast under fluorescent office lighting.

A cautionary story: A client once chose a stunning emerald cut in H color because she loved the shape and didn't understand how step-cut faceting reveals warmth. The diamond was beautiful in our display case under specialized lighting. Six weeks after her engagement, she called in tears—the ring looked yellow under the warm pendant lights at her office. We remade it with an F color stone, and she told me afterward that her confidence came back. "I was embarrassed to show people," she admitted. The lesson isn't that H color is wrong—it's that shape matters as much as grade.

How to Care for Lab Grown Diamonds

Caring for lab-grown diamonds follows the same principles as caring for natural stones with minor nuances. Clean your ring regularly using warm water, mild dish soap, and a soft toothbrush, or use an ultrasonic cleaner safe for lab-grown diamonds set in platinum or gold mountings. Avoid harsh chemicals including chlorine bleach that could damage prongs or discolor gold alloys. Remove your ring during weightlifting, gardening, or activities that might expose it to impact or abrasive surfaces.

Annual professional cleaning maintains the setting and ensures prongs remain secure. Ultrasonic cleaning is generally safe for lab-grown diamonds in solid metal settings, though avoid ultrasonic cleaning if your ring contains clarity-enhanced stones, included melee, or fragile antique settings. At StoneBridge, we offer complimentary cleaning for all purchases, helping your pavé or solitaire ring stay brilliant for years.

Matching Wedding Bands and Engagement Rings

Couples choosing matching bands often ask how to coordinate color grades between pieces. The general principle: your wedding band should match or slightly exceed your engagement ring's color grade to maintain visual harmony. An F color engagement ring in a cathedral setting pairs beautifully with an F or E color wedding band in the same 14K white gold metal.

Marriage bands featuring pavé diamonds require particular attention to color coordination. The small accent stones should complement your engagement center stone precisely. If your engagement ring features an F color center, consider F or G color melee for the band. Lower grade accents may appear noticeably different against a higher grade center stone under jewelry case lighting.

Eternity bands present unique challenges because the stones wrap entirely around the ring. Any color inconsistency becomes visible from multiple angles in a channel set or rub-over design. We recommend selecting the highest practical color grade for eternity bands—ideally F or E—and ensuring all stones come from the same production batch when possible for optimal matching.

His and Hers Matching sets offer opportunities to coordinate without requiring identical specifications. A man's marriage band might feature no diamonds or smaller accent stones in a brushed 14K yellow gold comfort fit design, allowing flexibility in metal choice while maintaining visual connection through matching width and finish.

One couple came to us for their tenth anniversary—she wanted to surprise him with a matching band to wear alongside her original engagement ring. We spent an afternoon color-matching her D color center stone with accent stones for his band. When he saw them side by side at dinner that night, he teared up. "Ten years and she still makes me feel like the luckiest guy alive," he told me the next day. Matching bands aren't just about aesthetics—they're about honoring the original promise with a new chapter.

Unique Lab Grown Diamond Rings for Wedding Bands

Wedding bands with lab-grown diamonds have become increasingly popular as couples seek cohesive sets for anniversary celebrations. Lab-grown diamond necklaces and earrings also make excellent anniversary gifts, allowing couples to build matching jewelry collections over time with coordinated color grades.

The affordability of lab-grown stones means you can choose F or E color grades throughout your jewelry set without budget strain. A complete bridal set with matching color grades and consistent 14K white gold or 950 platinum creates a polished, intentional appearance in photographs and daily wear.

Common Mistakes to Avoid When Selecting Diamond Color

Overpaying for invisible differences ranks among the most frequent errors buyers make when selecting engagement rings. Spending premium prices for D color when E or F would appear identical wastes resources that could improve other specifications in your pavé setting or three-stone design. Before paying for the highest grade, compare stones side-by-side under various lighting conditions. You may find that your eyes simply cannot perceive the difference you're being asked to pay for in a prong or bezel setting.

Neglecting cut quality in pursuit of higher color grades harms your diamond's beauty more than any color grade improvement could help. A poorly cut D color diamond with a pavilion angle of 41.2° will look inferior to an excellently cut F color stone with ideal 40.6° pavilion in almost every lighting condition. Always prioritize cut—it's the factor that most directly affects visual appeal in any ring style.

Failing to consider metal setting effects means missing opportunities to optimize your budget. Yellow gold settings in 14K or 18K let you choose G or H color grades while achieving F color appearance. This knowledge alone could save you $1,500-$3,000 on a 1.5ct lab-grown stone while delivering identical visual results in a vintage-inspired mounting.

Avoid purchasing without comparing stones in person whenever possible. Photographs and videos cannot capture color perception accurately, especially for stones under 1 carat. Visit a jeweler, examine multiple options in the same setting type, and trust your own eyes rather than relying solely on GIA or IGI certificates and written specifications.

One client learned this lesson the hard way. She ordered a ring online based on certification specs alone—D color, VS1, excellent cut. When it arrived, the ring was gorgeous on paper but the stone looked flat in person. We examined it under our loupe and found the proportions technically fell within "excellent" ranges but sat at the outer edges—technically compliant, visually underwhelming. She exchanged it for an F color stone with proportions at ideal center points. "The first one looked like a diamond," she said. "This one sparkles like one."

Making Your Perfect Color Choice

D, E, and F color grades all represent exceptional quality certified by industry-leading laboratories. D stands alone at the absolute top for those prioritizing maximum purity and documented specifications for insurance purposes. E delivers virtually identical appearance at a more accessible price point, typically saving $800-$1,500 on a 1ct lab-grown stone with IGI certification. F offers the best value proposition for most buyers, appearing completely colorless in virtually all conditions while costing significantly less than D grades.

For couples selecting engagement rings, anniversary bands, or any piece where colorless beauty matters, we recommend prioritizing F color combined with excellent cut quality in a 14K white gold or 950 platinum setting. This combination maximizes visual impact while respecting practical budget constraints, allowing you to allocate savings toward a larger carat weight or pavé accents.

Lab-grown diamonds have made high color quality more accessible than ever, allowing more couples to enjoy D-F grades without the scarcity premiums historically attached to these specifications. The choice between Lab-Grown and Natural ultimately reflects personal values around sustainability, investment considerations, and tradition.

The ring you choose will mark the moment someone became your partner, the promise you made on your wedding day, the milestone you celebrate year after year. Whether that ring holds a D color stone or an F color stone matters far less than what it represents—the love you're committing to honor.

Explore StoneBridge Jewelry's curated collection of engagement rings and wedding bands to discover how our selection of GIA and IGI certified diamonds can help you find the perfect stone for your special moment. Our team stands ready to guide you through every specification—color grade, cut quality, carat weight, and setting preferences—so your choice reflects both your aesthetic taste and your practical values.

Frequently Asked Questions

Is F color good enough for an engagement ring? F color diamonds rank among the best choices for engagement rings in any setting type. Under normal viewing conditions, F graded stones appear completely colorless, indistinguishable from D or E grades to the naked eye. This grade offers the ideal balance of premium quality and practical value for most couples planning their proposal with a budget of $3,000-$6,000 for a 1ct lab-grown stone.

Which is better: E or F color diamond? Both E and F represent excellent color grades that appear colorless to consumers and professionals alike. The microscopic difference between them is detectable only through sophisticated instrumentation in controlled conditions. E color justifies higher prices only for buyers with specific insurance documentation requirements or those who must have the absolute highest available grade certified by GIA or IGI.

Do lab-grown diamonds have color grades? Yes, lab-grown diamonds receive the same standardized GIA color grading scale as natural diamonds. GIA, IGI, and GCAL all certify lab-grown stones using identical criteria, evaluating them against the same D-Z color scale under controlled lighting. Most lab-grown diamonds consistently achieve F or better color due to controlled production conditions that minimize trace nitrogen.

What color grade can I skip in a yellow gold setting? Yellow gold settings in 14K or 18K mask diamond color effectively, allowing buyers to consider G or even H color grades without visible warmth in a cathedral or vintage setting. The metal's warmth complements subtle body color in the diamond, creating harmonious appearance rather than visible contrast. This lets you allocate savings toward 0.5-1 carat additional weight or a more elaborate pavé band.

How does diamond certification affect color grade accuracy? Independent certification from GIA, IGI, or GCAL ensures your diamond's color grade has been evaluated objectively by trained gemologists using standardized 6500K lighting conditions. This verification protects you from inaccurate seller claims and provides documentation for insurance appraisals and resale purposes. Always purchase certified diamonds to ensure you're receiving the color grade you're paying for.
