Introduction to Lab Grown Diamond Clarity Grades

Clarity confuses nearly everyone shopping for a Lab Grown Diamond engagement ring. Here's the truth nobody tells you: that tiny inclusion inside your stone might matter more than its carat weight or color grade.

I watch couples make the same mistake daily. They obsess over size. They debate between D and F color. Then they discover inclusions hiding inside their diamond affect brilliance—and they've already spent their entire budget.

One couple came to us wanting a statement ring for their tenth anniversary. They'd done their homework on color grades, memorized the D through Z scale, and had their hearts set on a G-color stone. When I pulled up the certification report, they hadn't looked at the clarity grade once. Their "perfect" diamond had inclusions running directly through the center table. The ring sat in a drawer for six months while they saved for a replacement. Don't let that happen to your milestone moment.

Worth every penny? Not if you didn't understand what you bought.

A 1.5ct E-VS2 round brilliant cut in a cathedral setting with pave band typically costs $3,200-$4,800 from reputable retailers. Compare that to $8,000-$15,000 for an equivalent mined stone. Lab Grown Diamonds often provide exceptional clarity at more accessible price points. At StoneBridge, we've guided thousands of couples toward Sustainable Engagement Rings that balance stunning visuals with real value. This guide covers the GIA clarity grading scale, what each grade means for Lab Grown Diamonds specifically, and practical guidance for making a confident purchasing decision for your wedding bands or anniversary rings.

By the end, you'll know exactly how gemologists evaluate inclusions, which grades offer the best value for different diamond shapes, and why IGI or GCAL certification matters for every ethical diamond jewelry purchase.

Understanding the GIA Clarity Grading Scale

The Gemological Institute of America developed the clarity grading system that became the worldwide standard for evaluating both mined and Lab Grown Diamonds. This scale assesses blemishes on the stone's surface and internal inclusions that occur during formation, using 10x magnification as the standard viewing condition.

The Six Clarity Categories

Every diamond receives one of six classifications based on characteristics visible under 10x magnification:

1. Flawless (FL) — No internal or external imperfections detectable
2. Internally Flawless (IF) — No internal inclusions, minor surface blemishes only
3. Very Very Slightly Included (VVS1/VVS2) — Tiny inclusions extremely difficult to locate
4. Very Slightly Included (VS1/VS2) — Minor inclusions observable with effort
5. Slightly Included (SI1/SI2) — Noticeable inclusions under magnification
6. Included (I1/I2/I3) — Obvious inclusions affecting transparency and brilliance

What Gemologists Actually See

Inclusions are essentially birthmarks that form during a diamond's creation. For Lab Grown Diamonds, the inclusion types often relate to their growth method—CVD stones may show dark carbon spots while HPHT stones display metallic flux remnants.

Gemologists examine stones using 10x magnification, illuminating the diamond from below to reveal internal characteristics. They note the size, number, position, nature, and relief of inclusions when assigning grades, following strict GIA protocols established in 1953.

How do graders spot what you cannot see? Training and lighting conditions create the difference.

Type IIa vs Type I Lab Grown Diamonds

Most Lab Grown Diamonds fall into the Type IIa category, meaning they lack nitrogen or boron impurities. This classification often indicates higher purity and can contribute to superior clarity grades. Type IIa stones represent less than 2% of all mined diamonds but constitute the majority of lab grown production. This distinction matters when comparing stones, as Type IIa Lab Grown Diamonds frequently exhibit exceptional transparency.

Lab Grown Diamond Clarity Chart: From FL to I3

The clarity chart below provides a detailed breakdown of what you can expect at each grade level when shopping for Lab Grown Diamond jewelry.

Flawless (FL) and Internally Flawless (IF)

These represent less than 1% of all diamonds. FL stones show absolutely no inclusions or blemishes under any magnification. IF diamonds display minor surface characteristics that a skilled grader can remove through polishing. For practical purposes, both appear identical to the naked eye.

A 2ct FL round brilliant in 950 platinum typically costs $12,000-$18,000. An equivalent VS1 stone runs $5,500-$7,500. The price premium for these grades often exceeds the visual benefit, especially for everyday wear pieces like wedding bands.

Pay for perfection you cannot see? Your call.

Very Very Slightly Included (VVS1/VVS2)

VVS1 inclusions sit in less visible areas (bottom or side facets), while VVS2 inclusions may appear in slightly more noticeable positions. Under 10x magnification, finding these tiny traces requires significant expertise. Most buyers cannot detect any difference between VVS stones and higher grades without specialized equipment.

For step-cut shapes like emerald or Asscher cuts, VVS grades provide insurance against visible inclusions—large open facets in these cuts reveal inclusions more readily than brilliant-cut stones.

Very Slightly Included (VS1/VS2)

These grades offer the sweet spot for many buyers. VS1 diamonds have inclusions that are small and localized, typically requiring 10x magnification to identify. VS2 stones may show inclusions visible under magnification, but experienced graders can still locate them with some difficulty.

For brilliant-cut round diamonds, VS2 and even SI1 grades often appear eye-clean, meaning no inclusions are visible without magnification. A 1.2ct F-VS2 round brilliant in a six-prong 14K white gold solitaire setting delivers exceptional visual quality at $3,400-$4,200.

Slightly Included (SI1/SI2)

SI1 represents the most popular clarity tier for value-conscious buyers. Inclusions become visible under standard 10x magnification, and in some cases, certain SI1 stones may show flaws to the naked eye—especially with larger carat weights above 1.5ct or in step-cut shapes.

A bride recently told me she cried when she first saw her engagement ring—not from joy, but panic. The sparkle seemed different than she'd imagined. When I examined her stone, the inclusions sat directly under the center table, visible in the proposal photos she'd posted online. She loved her fiancé, loved the moment—but for months afterward, every glance at her ring reminded her of what she wished she'd known. The ring got upgraded at her first anniversary. The memory didn't.

SI2 inclusions are more obvious and may affect light performance in certain lighting conditions. A 1ct G-SI1 oval cut in a bezel setting with 18K yellow gold band costs approximately $1,800-$2,400. Always review SI-graded stones with a jeweler or examine certification diagrams carefully to verify inclusion position.

Included (I1/I2/I3)

These grades indicate inclusions visible without magnification. I1 diamonds may have inclusions that don't significantly impact durability, while I2 and I3 stones feature more extensive characteristics affecting both appearance and structural integrity. We typically recommend avoiding these grades for engagement rings or wedding bands intended for daily wear.

Grade	Inclusions Visible at 10x	Eye Clean	Best Value For
FL/IF	None	Yes	Collectors
VVS1/VVS2	Extremely difficult	Yes	Step-cut shapes
VS1/VS2	Difficult	Usually	Most engagement rings
SI1/SI2	Visible	Sometimes	Budget-conscious buyers
I1/I2/I3	Obvious	No	Not recommended

How Lab Grown Diamonds Are Certified

Certification ensures you're getting exactly what you pay for when purchasing Lab Grown Diamond jewelry. Unlike natural diamonds, which may come from various grading sources, lab grown stones typically receive evaluation from specific laboratories equipped for their unique characteristics.

Leading Certification Laboratories

GIA (Gemological Institute of America) — The most recognized name in gemology now grades Lab Grown Diamonds using identical standards applied to mined stones. Their reports include specific notations distinguishing lab grown origin and growth method (HPHT or CVD).

IGI (International Gemological Institute) — The most common certifier of Lab Grown Diamonds. IGI provides detailed clarity mappings showing exact inclusion locations, sizes, and types. Over 70% of lab grown diamonds sold worldwide receive IGI certification.

GCAL (Gem Certification and Assurance Lab) — Known for rigorous standards and superior imaging documentation. GCAL offers 8x enlargement diagrams that clearly show inclusion positions.

What Your Certification Report Shows

A quality Lab Grown Diamond report includes:

• The 4Cs: Cut, Color, Clarity, and Carat weight
• Dimensions and proportions diagram
• Clarity plot map showing inclusion locations and types
• Fluorescence rating
• Growth method (CVD or HPHT)
• Polish and symmetry grades

Why Certification Matters for Ethical Purchases

When buying sustainable engagement rings, certification provides transparency about the diamond's origin and quality. Reputable sellers always provide documentation from independent laboratories like IGI or GCAL. At StoneBridge, every Lab Grown Diamond comes with certification, giving you confidence in your ethical diamond jewelry purchase.

Lab Grown vs Natural Diamond Clarity: Key Differences

Understanding the distinction between lab grown and natural diamond clarity helps you make smarter purchasing decisions.

Similarities in Grading

Both lab grown and natural diamonds use the same GIA clarity scale. A VS1 is a VS1 regardless of origin. The grading process, magnification requirements, and category definitions apply equally to both types. An IGI-certified 1.5ct E-VS1 Lab Grown Diamond meets the same clarity standards as a GIA-certified 1.5ct E-VS1 mined diamond.

Differences in Inclusions

Lab Grown Diamonds often display fewer and different inclusion types compared to mined stones. CVD (Chemical Vapor Deposition) grown diamonds may show dark carbon spots or graphite clusters, while HPHT (High Pressure High Temperature) stones might display metallic flux inclusions or growth patterns. Natural diamonds typically contain mineral crystals, feathers, or cloud formations from their geological formation over billions of years.

The Value Proposition

Lab Grown Diamonds genuinely shine in this area. You can often purchase a higher clarity grade for the same budget. A 1ct F-VS1 lab grown diamond costs approximately $2,800-$4,200, while an equivalent mined stone runs $5,500-$8,000. Where a mined VVS1 might cost significantly more, a lab grown VVS1 offers the same visual quality at 30-50% lower prices. This value advantage extends throughout the clarity spectrum, making premium grades more accessible.

Lab Grown Diamonds vs Moissanite

Some shoppers confuse moissanite with Lab Grown Diamonds. Moissanite is a distinct gemstone (silicon carbide) with different optical properties. It displays more fire and rainbow reflections than diamonds. When comparing clarity, moissanite ranks around 9.25 on the Mohs hardness scale versus diamond's perfect 10, and its clarity evaluation uses different standards entirely.

Confused about the difference? You're not alone—but verification matters.

Always verify you're purchasing actual Lab Grown Diamonds when diamond specifications matter to you.

Choosing the Right Clarity Grade for Your Budget

Maximizing value requires matching clarity grades to your specific situation—diamond shape, ring setting, and wearing habits all factor into the ideal choice.

Best Clarity Grades by Budget Level

Under $1,500 — Focus on SI1 grades with round brilliant cuts. At this price point, you'll prioritize carat weight while ensuring the stone remains eye-clean. A 0.90ct G-SI1 round brilliant in a four-prong 14K white gold solitaire setting typically costs $1,200-$1,400. Request a clarity plot diagram to verify inclusion positions.

$1,500 - $3,500 — VS1-VS2 grades become achievable. A 1.3ct G-VS2 princess cut in a cathedral setting with diamond-accented shank runs $2,800-$3,400. This range suits most engagement ring needs, providing beautiful stones without unnecessary premium payments for grades you'll never appreciate visually.

$3,500+ — Consider VVS1-VVS2 for step-cut shapes or if you simply prefer knowing your stone ranks among the clearest available. A 2ct D-VVS1 emerald cut in a bezel setting with 950 platinum band costs approximately $5,500-$7,000.

Why VS1-VS2 Often Represents Optimal Value

For daily-wear pieces like engagement rings and wedding bands, VS grades deliver nearly flawless appearance at reasonable prices. A 1.5ct H-VS1 round brilliant in a pavé halo setting with 18K rose gold band provides exceptional beauty at $4,200-$5,500. You're paying for theoretical perfection you cannot see rather than practical beauty you can appreciate daily.

Shape Matters for Clarity Selection

Diamond shapes interact differently with light and can mask or reveal inclusions:

• Round brilliants hide inclusions best due to their faceting pattern
• Princess cuts also conceal inclusions reasonably well
• Emerald and Asscher cuts show inclusions more easily due to step-cut facets
• Oval and pear shapes distribute light in ways that minimize visible flaws

For emerald-Cut Engagement Rings, we recommend VS1 or higher. For round brilliant cuts, SI1 grades can work beautifully when inclusions position favorably under side facets rather than the table.

Lab Grown Diamond Clarity for Special Occasions

Different jewelry purchases warrant different clarity priorities. Matching your clarity selection to the occasion ensures your gift makes the impression you intend.

Valentine's Day Diamond Jewelry

When selecting Valentine's Day Diamond gifts, clarity matters more for pieces featuring center stones. Diamond studs or pendant necklaces benefit from VS1-VS2 grades, ensuring brilliance catches every romantic lighting. A 0.80ct total weight diamond stud earring set in 14K yellow gold with E-VS1 stones costs approximately $1,400-$1,800. Accent stones in pavé settings can drop to SI1-SI2 without noticeable impact to overall appearance.

Wedding Bands with Lab Grown Diamonds

Matching wedding bands often incorporate smaller accent diamonds rather than large center stones. For these pieces, durability matters as much as clarity. Look for SI1-SI2 grades in melee diamonds (small accent stones under 0.20 carats) where inclusions rarely impact appearance or longevity.

A channel-set 18K white gold wedding band with 0.50ct total weight melee diamonds typically costs $800-$1,200.

Anniversary Rings and Eternity Bands

Anniversary rings and eternity bands feature diamonds continuously around the shank. Because many stones are visible, consistency matters more than individual grade. VS2-SI1 works well for these pieces, balancing visual uniformity with practical pricing.

A 2mm platinum eternity band with 1.5ct total weight G-VS2 round brilliants costs approximately $3,200-$4,500.

Unique Lab Grown Diamond Rings for Proposals

Unique Lab Grown Diamond Rings for proposals deserve careful clarity consideration based on setting style. Three-stone rings require attention to each stone's grade—consider matching D-F colors with VS1-VS2 clarities for each stone. Solitaire settings concentrate focus on one stone, making clarity more critical. Halo settings can utilize slightly lower clarity center stones, as surrounding accents mask some characteristics.

A 1.2ct center stone with halo in a split-shank 950 platinum setting at G-VS1 typically ranges $4,500-$6,000.

How Are Lab Grown Diamonds Made and Why It Affects Clarity

The production method influences which inclusions appear in your Lab Grown Diamond. Understanding these processes helps explain why certain clarity grades are more common in lab grown versus mined stones.

Chemical Vapor Deposition (CVD) Process

CVD diamonds grow inside a chamber filled with carbon-rich gas at temperatures between 800-900°C. The process deposits carbon atoms onto a seed crystal layer by layer over several weeks. Typical inclusions in CVD stones include:

• Dark spots (unconverted carbon)
• Graphite inclusions
• Strain patterns visible under polarized light
• Growth lines or striations
• Silicon carbide remnants from seed plates

Advancing technology has significantly reduced inclusion frequency in CVD diamonds, making high-clarity stones (VS1 and above) more consistently achievable in modern production.

High Pressure High Temperature (HPHT) Process

HPHT mimics the extreme conditions where natural diamonds form deep within Earth's mantle. Carbon experiences pressures exceeding 5 GPa and temperatures above 1500°C around a metal catalyst (typically iron, nickel, or cobalt). HPHT inclusions often include:

• Metallic flux remnants visible under magnification
• Graphite along healing fractures
• Unique color zoning in fancy colored stones
• Internal strain patterns

HPHT stones may display characteristic metallic inclusions visible under magnification. Many appear as small dark spots or needle-like shapes, sometimes showing magnetic properties due to iron-nickel metal catalyst remnants.

Manufacturing Advances Improving Clarity

The sustainable engagement ring industry benefits from continuous manufacturing improvements. Modern chambers provide more stable environments with tighter temperature and pressure control, resulting in fewer inclusion-forming events. Seed selection has become more sophisticated, promoting cleaner growth patterns. These advances mean today's lab grown diamonds achieve higher clarity grades more consistently than those produced even three years ago.

60% of CVD stones now achieve VS1 or higher clarity.

Current production yields show approximately 60% of CVD stones achieving VS1 or higher clarity.

Caring for Your Lab Grown Diamond Based on Clarity

Proper maintenance preserves your diamond's brilliance regardless of clarity grade. However, certain considerations apply depending on your stone's inclusion profile.

General Cleaning Recommendations

Most lab grown diamonds respond well to gentle cleaning. Mix warm water with mild dish soap, soak for 20-30 minutes, then brush gently with a soft toothbrush. Ultrasonic cleaners are generally safe for lab-grown diamonds with VS1 clarity or higher, as these stones lack reaching inclusions or fractures that might trap cleaning solutions. Avoid harsh chemicals including chlorine bleach, which can damage metal settings.

Professional Maintenance

Stones with visible inclusions benefit from periodic professional inspection. A jeweler can identify any changes in inclusion characteristics that might affect durability. We recommend annual inspections for included stones, especially for pieces worn daily like engagement rings.

Professional cleaning using steam or ultrasonic equipment maintains brilliance in prong-set 14K white gold or 950 platinum mountings.

Caring for Different Jewelry Types

Diamond necklaces often accumulate oils from skin contact. Regular cleaning with a lint-free cloth maintains brilliance between professional cleanings. Earrings face less daily contact but may collect residue from hair products. Rings experience the most exposure to soaps, lotions, and physical contact—all of which can diminish shine over time.

A champagne-colored buildup in a cathedral setting indicates soap residue requiring attention.

Long-Term Preservation

Store ethical diamond jewelry separately to prevent scratching. Even though diamonds rank hardest on the Mohs scale at 10, they can scratch other diamonds or softer gemstones. Consider fabric-lined compartments or individual soft pouches for each piece. Avoid storing pieces with pave settings together, as prong damage can occur from contact.

Celebrity Influence on Lab Grown Diamond Trends

Celebrity choices shape consumer preferences in ways both subtle and dramatic. The sustainable engagement ring movement gained significant momentum from high-profile lab grown diamond adoption.

Celebrity Lab Grown Engagement Rings Driving Interest

When prominent figures chose lab grown diamonds for their proposals, public interest surged accordingly. These choices normalized ethical diamond jewelry for mainstream audiences who previously associated lab grown stones with lower quality. The conversation shifted from whether to consider lab grown options to how to select the best ones.

Trending Clarity Preferences Today

Current trends show buyers prioritizing:

• VS1-VS2 clarity for standard engagement rings (most popular choice)
• VVS grades for three-stone and halo settings
• Larger carat weights at VS-SI clarity rather than smaller stones at FL-VVS
• HPHT stones for colorless D-F grades, CVD stones for near-colorless G-H grades

The focus has moved toward visible beauty rather than technical perfection invisible to the naked eye.

Colored Lab Grown Diamonds

Fancy Colored Lab Grown diamonds introduce unique clarity considerations. Deep colors can mask certain inclusions, allowing buyers to consider lower clarity grades than they would for white diamonds.

Yellow and pink lab grown diamonds often appear stunning in VS-SI grades, making premium colors more accessible price-wise.

A 1ct fancy vivid pink VS2 cushion cut in a rose gold bezel setting costs approximately $3,500-$5,000.

Common Mistakes When Evaluating Diamond Clarity

Avoiding these pitfalls helps you make smarter purchasing decisions and prevents common regrets.

Mistake 1: Assuming Higher Grade Means Better Appearance

Flawless diamonds look identical to VS2 stones under normal viewing conditions. The differences exist only under 10x magnification by trained graders. A 2ct D-FL round brilliant appears exactly the same as a 2ct D-VS2 stone in an three-stone setting with side diamonds, yet costs 40-60% more.

Mistake 2: Overlooking Inclusion Position

A small inclusion positioned under a side facet may remain invisible even in SI1 grades. The same inclusion under the table facet (center of the diamond) becomes more apparent. Review clarity plots carefully to understand where characteristics appear.

Position matters more than size. An SI1 with inclusions under the culet (bottom point) is preferable to an SI1 with inclusions under the table.

Mistake 3: Ignoring Certification Details

Not all SI1 grades perform equally. Some contain inclusions visible to the naked eye; others appear nearly flawless. The certification diagram reveals specific inclusion types, sizes, and locations. A cloud-type inclusion in an SI1 may be less visible than a feather, which could affect durability. Always examine these details before purchasing.

Mistake 4: Prioritizing Clarity Over Cut

A poorly cut VS1 diamond may appear less brilliant than a well-cut SI1 stone. Cut quality affects light performance more dramatically than clarity grade. We recommend prioritizing cut grade first (aim for Excellent or Very Good), then selecting the highest clarity affordable within your remaining budget.

An ideal-cut G-SI1 round brilliant outperforms a poorly-cut E-VVS1 stone.

Mistake 5: Choosing the Wrong Setting for Your Stone

I remember a couple who selected a delicate pavé band for their SI2 diamond because they loved how it sparkled in the display case. What they didn't consider: pavé settings require diamonds to be nearly inclusion-free, or the tiny prongs holding each accent stone create pressure points that stress inclusions over time. Their stone developed a fracture within eight months. They switched to a sturdy bezel setting and haven't had a problem since. The lesson: clarity grade must work with your setting choice, not against it.

Balancing Clarity, Budget, and Personal Preferences

The perfect clarity grade depends on your specific situation. Your budget, diamond shape, setting style, and personal priorities all factor into the ideal choice. There's no universally correct answer—only what works best for you and your partner.

One couple recently shared that they still talk about the moment she put on her engagement ring for the first time. She didn't notice the clarity grade. She noticed how the light caught the stone when her fiancé knelt on one knee. She noticed his hands shaking. Three years later, she still notices how her ring catches light when she's stuck in traffic or washing dishes—the everyday moments that make a piece of jewelry truly yours.

Consider what you'll actually see and appreciate daily. For engagement rings worn constantly, practical beauty typically matters more than technical specifications. Your stone should bring joy every time you glance at it, regardless of what graders observe under magnification.

Frequently Asked Questions

What is the best clarity grade for a lab grown diamond engagement ring?

The best clarity grade depends on your budget and diamond shape. For round brilliant cuts, VS1-VS2 offers excellent value as inclusions are typically invisible to the naked eye. A 1.2ct F-VS2 round brilliant in a six-prong 950 platinum setting costs approximately $3,800-$4,800. For step-cut shapes like emerald or Asscher, consider VVS1-VVS2 since their large facets make inclusions more visible. Many couples find SI1 grades work beautifully for round cuts, provided inclusions position favorably under side facets rather than the table.

Are lab grown diamonds graded the same as natural diamonds?

Yes, lab grown diamonds undergo the same clarity grading process using the GIA scale. However, they're certified by specialized labs like IGI, GCAL, or GIA, which now grades lab grown diamonds with the same rigorous standards applied to natural diamonds. The grading criteria remain identical, ensuring consistent quality assessment across both origins.

Can you see inclusions in VS1 clarity lab grown diamonds?

VS1 (Very Slightly Included 1) diamonds typically have inclusions that are difficult to see even under 10x magnification. For most observers, VS1 diamonds appear completely clean to the naked eye, making them an excellent balance of quality and value. A 1.5ct E-VS1 oval cut in a pavé halo setting with 18K rose gold band demonstrates this visual quality at approximately $4,500-$5,800. The tiny characteristics present require significant expertise and magnification to identify.

How do I read a lab grown diamond clarity chart?

A clarity chart displays grades from Flawless (FL) at the top to Included (I3) at the bottom. Higher grades indicate fewer or smaller inclusions visible under magnification. Look for eye-clean grades (typically VS2 and above for most shapes) to ensure no visible flaws without magnification. The chart helps you understand relative quality and pricing expectations—expect to pay approximately $1,200-$2,000 more for each clarity grade improvement in the VS range.

Do lab grown diamonds have fewer inclusions than natural diamonds?

Lab grown diamonds often exhibit fewer visible inclusions due to controlled manufacturing environments. However, they can have unique inclusion types specific to their growth method (CVD or HPHT). Both lab grown and natural diamonds are graded on the same scale, so a VS1 lab grown diamond has equivalent clarity to a VS1 natural diamond when viewed under identical conditions. Lab grown stones lack the feather-type inclusions common in mined diamonds, which can affect durability in some cases.

How should I care for my lab grown diamond ring?

Clean your lab grown diamond regularly using warm water and mild dish soap. Ultrasonic cleaners are safe for stones with VS1 clarity or higher—modern ultrasonic cleaners operating at 40kHz effectively clean lab-grown diamonds without damaging stones that lack reaching inclusions. Soak for 20-30 minutes, then brush gently with a soft toothbrush. Avoid ultrasonic cleaners if your stone has SI1 or lower clarity with visible fractures. Annual professional inspections help catch any changes that might affect durability, especially for rings worn daily.

What diamond shapes hide inclusions best?

Round brilliant cuts hide inclusions best because their faceting pattern reflects light in ways that mask internal characteristics. A 1.3ct G-SI1 round brilliant in a six-prong solitaire setting appears eye-clean in most lighting conditions. Princess cuts also perform well due to their angular faceting. Step-cut shapes like emerald and Asscher reveal inclusions more easily due to their large, open facets—a 1.5ct D-VS2 emerald cut in a bezel 950 platinum setting showcases why step-cuts require higher clarity grades. If you want flexibility with clarity grades, round brilliant cuts give you the most room to work with.
