Why the 4Cs Matter for Lab Grown Diamond Solitaire Shoppers

Choosing a diamond engagement ring marks one of the most significant jewelry purchases you'll ever make. One couple came to us wanting a showstopper—they'd saved for two years and had $10,000 burning a hole in their pocket. The husband-to-be was certain bigger meant better until we showed him a 1ct Excellent-cut stone beside a 1.8ct with middling proportions. The smaller diamond blazed with life while its larger cousin looked flat and tired. That moment changed everything about how they approached their search.

The 4Cs—cut, color, clarity, and carat—provide the universal vocabulary for evaluating any diamond. Lab created options often achieve higher clarity grades (VVS1-VS1) and superior color ratings (D-F) because their controlled growth environment minimizes natural imperfections. This means you can stretch your budget further while securing a 1.2ct F-VS2 round brilliant that rivals natural stones in the 4C categories.

Many first-time buyers assume Lab Grown Diamonds differ fundamentally in quality from their mined counterparts. They don't. Lab and mined diamonds share identical chemical, physical, and optical properties—both ranking 10 on the Mohs hardness scale. if you are searching for wedding bands with lab grown diamonds, an anniversary ring, or that iconic proposal ring set in 14K white gold or 950 platinum, Understanding the 4Cs empowers you to make confident decisions aligned with your values and budget.

Understanding the Diamond 4Cs: Cut, Color, Clarity, and Carat

Every certified diamond receives evaluation across four standard criteria—the famous 4Cs established by the Gemological Institute of America (GIA). These grades determine beauty, Quality, and Value if you are examining a lab grown or natural stone certified by GIA, IGI, or GCAL.

Cut refers to how precisely a diamond's facets interact with light. This single factor most dramatically affects sparkle and brilliance. A well-cut diamond returns light through its crown, creating that coveted fire and scintillation. Proportions matter critically—a table percentage of 54-57% and depth of 60-62.5% represent ideal ranges for round brilliants.

Color measures the presence of yellow or brown tones in white diamonds. The GIA scale ranges from D (completely colorless) to Z (light yellow or brown). Colorless diamonds are rarest and most valuable, though many lower-color grades appear entirely white when set in yellow gold mountings.

Clarity grades evaluate internal inclusions and external blemishes. Since diamonds form under immense heat and pressure, most contain microscopic characteristics. Clarity ranges from FL (flawless) to I3 (included), with most retail diamonds falling between VS1 and SI2. Lab grown stones frequently achieve VS1-VS2 clarity due to controlled formation conditions.

Carat measures diamond weight, not size. One carat equals 0.2 grams. Larger carat weights cost more per carat due to rarity—diamonds above one carat become exponentially more valuable than smaller stones of identical quality.

Lab Grown Diamonds typically deliver better 4C performance per dollar spent. Where a mined diamond of equal specifications might cost $15,000, a lab created equivalent often ranges $5,000-$8,000. A 1.5ct E-VS1 lab diamond priced at $6,200 would cost approximately $18,000-$22,000 in mined form. This pricing advantage lets you prioritize cut quality or increase carat weight substantially.

The Cut: Why Proportions Matter Most for Solitaire Rings

Of all four Cs, cut wields the greatest influence over a diamond's visual appeal. A bride recently told me her engagement ring stopped her heart for a moment—the way light danced off her stone when her fiancé knelt on one knee. That magic comes entirely from cut quality. Here's what nobody tells you: even a flawless, colorless stone appears dull and lifeless with poor proportions. A well-cut diamond with minor inclusions can display stunning brilliance.

The GIA assigns cut grades for round brilliant diamonds: Excellent, Very Good, Good, Fair, and Poor. Industry experts recommend targeting Excellent or Very Good cuts for solitaire rings, where the diamond stands alone in a classic 4-prong platinum setting to showcase its beauty. Fair and Poor cuts sacrifice sparkle unnecessarily.

Cut quality affects light performance in three ways: brilliance (white light return), fire (colored light dispersion), and scintillation (pattern of light and dark areas as the diamond moves). A diamond's crown angle (typically 33-36 degrees), table percentage, pavilion depth (42-44% optimal), and girdle thickness all determine how light travels through the stone.

Popular cuts for engagement rings include the round brilliant with its 58 facets, which maximizes light return, and fancy shapes like oval, pear, and princess cuts that offer distinct visual profiles. Oval diamonds create an elegant elongated appearance that flatters smaller hands. Princess cuts deliver contemporary geometry with impressive brilliance. For active lifestyles, lower-profile settings like bezel or semi-bezel protect the stone while maintaining elegance.

When shopping for a diamond solitaire engagement ring, prioritize cut above all other factors. You'll notice the difference immediately—a poorly cut diamond looks flat regardless of its color or clarity grades. A 1ct Excellent-cut diamond will outshine a 1.5ct Poor-cut stone every time.

Color and Clarity: Finding the Right Balance

For most solitaire ring buyers, the ideal color range falls between D and H. Diamonds graded D-F appear completely colorless—a luxury designation visible mainly under controlled lighting. G-H grades present near-colorless appearance at substantially lower price points. Unless you're comparing side-by-side with higher grades, most observers cannot detect warmth in G-H diamonds, especially in yellow gold settings.

Color becomes less critical in certain settings. Yellow gold mountings (14K or 18K) can mask lower color grades effectively, while platinum and white gold pair best with D-G rated diamonds. Rose gold settings also complement warmer color grades beautifully. This knowledge helps you allocate budget toward cut quality rather than unnecessary color premiums.

Clarity evaluation follows similar logic. Stones graded VS1 (Very Slightly Included) and VS2 contain inclusions invisible to the unaided eye. SI1-SI2 grades may show slight inclusions under magnification or specific lighting conditions. For everyday wear in an engagement ring set in 14K white gold, these clarity levels represent excellent value.

Lab Grown Diamonds frequently achieve higher clarity grades than mined stones because their controlled formation produces fewer inclusions. CVD-grown diamonds sometimes display subtle characteristics visible under 10x magnification, but these rarely impact beauty or durability. HPHT stones may show metal catalyst inclusions from the production process. You can confidently select VS1-VS2 clarity without worrying about visible imperfections.

How Are Lab Grown Diamonds Made? Quality Behind the Sparkle

Lab Grown Diamond production methods infographic">

Two primary methods produce Lab Grown Diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both processes recreate the natural conditions that form diamonds deep within Earth's mantle, just on accelerated timelines measured in weeks rather than geological ages.

HPHT technology subjects carbon to approximately 1,500°C and 5-6 GPa of pressure—conditions matching natural diamond formation. A diamond seed sits within a metal solvent (typically iron, nickel, or cobalt) that dissolves carbon, which then crystallizes onto the seed. This method often produces diamonds with distinctive color characteristics and works particularly well for creating fancy colored stones in pink, blue, and yellow hues.

CVD growth places diamond seeds in a sealed chamber filled with carbon-rich gas (methane and hydrogen). Microwave energy activates the gas, causing carbon atoms to deposit layer by layer onto the seed. This slower process (typically 2-4 weeks for a 1ct stone) produces diamonds with exceptional clarity and dominates commercial production for white diamonds.

Research from gemological institutes confirms both methods yield diamonds indistinguishable from mined stones without specialized testing equipment. Lab Grown Diamonds register as genuine diamonds on thermal conductivity meters and display identical properties under standard gemological examination. Both HPHT and CVD diamonds achieve GIA or IGI certification with the same grading standards applied to mined stones.

The growth method may influence certain 4C characteristics. HPHT diamonds sometimes show metal catalyst inclusions from the process, while CVD stones occasionally display color zoning. Certified lab diamonds undergo rigorous grading that identifies these characteristics, ensuring transparency for buyers.

Lab Grown vs Natural Diamonds: Comparing the 4Cs

Price comparisons between Lab Grown and Natural diamonds reveal significant advantages for the lab-created option. Lab diamonds cost approximately 30-50% less than natural stones with matching specifications. A one-carat, VS1 clarity, F-color natural diamond might retail for $12,000-$18,000 depending on retailer and cut quality. An equivalent Lab Grown Diamond typically ranges $5,000-$8,000—a savings of $7,000-$10,000.

This pricing structure opens possibilities previously constrained by budget. I remember a customer who teared up when she realized she could afford the 1.5ct ring she'd always dreamed of instead of settling for something smaller. Her fiancé had been worried about finances, but the lab diamond choice meant he could propose with the ring that matched his vision of her—something elegant and substantial, not modest. Couples can select higher cut grades, larger carat weights, or superior color and clarity within their original budget allocation. With $8,000, you might secure a 1.5ct G-VS2 lab diamond versus a 0.80ct with mined equivalents. The value proposition becomes particularly compelling for two-carat and three-carat solitaire rings, where natural diamond prices escalate to $25,000-$50,000+ while lab equivalents remain $10,000-$18,000.

Lab Grown Diamonds offer greater availability of higher grades. Natural diamonds with VVS1-VVS2 clarity and D-E color are extraordinarily rare and command premium prices. Lab production can consistently achieve these specifications, making exceptional quality more accessible. A D-Flawless lab diamond costs a fraction of its mined counterpart.

Resale value remains a consideration worth acknowledging. Natural diamonds have historically retained value better than lab grown alternatives, though the market continues evolving. Lab diamonds currently resell at approximately 30-50% of original purchase price versus 50-70% for natural stones. If future resale represents a primary concern, discuss this openly with your partner before making a decision.

Lab diamond adoption is accelerating rapidly. Major retailers report Lab Grown Diamond Engagement Ring sales increasing 20-30% year-over-year, with younger buyers particularly drawn to the ethical and environmental advantages. Industry analysts project continued growth through 2026 and beyond.

Choosing the Perfect Diamond Shape for Your Solitaire

Diamond shape dramatically influences a solitaire ring's In practical terms, appearance and perceived value. Each shape offers distinct characteristics suited to different lifestyles and aesthetic preferences. Shape selection affects carat appearance—fancy cuts often appear larger than round diamonds of equivalent weight.

Round brilliant remains the most popular choice, accounting for approximately two-thirds of all diamond sales. Its 58-facet design maximizes light return and works universally across Engagement Ring Styles, from classic 4-prong solitaire in platinum to contemporary cathedral settings with pave bands.

Oval diamonds have surged in popularity following celebrity lab grown engagement ring choices. Their elongated shape creates a flattering appearance on most hands while offering approximately 10% more surface area than round diamonds of equivalent carat weight. Oval cuts pair beautifully with halo settings in 14K white gold.

Emerald cuts feature step-cut facets that create hall-of-mirrors effect rather than sparkle. This Art Deco-inspired shape emphasizes clarity and transparency, making it ideal for higher-grade diamonds (D-F color, VVS1-VS1 clarity recommended). The open table reveals more of the stone, requiring better clarity grades.

Cushion cuts combine vintage charm with modern brilliance. Their rounded corners and large facets produce soft, romantic sparkle that photographs beautifully. Antique cushion cuts feature crushed ice facet patterns, while modern cushions offer chunkier scintillation.

Pear-shaped diamonds offer unique elegance with their teardrop silhouette. This shape flatters elongated fingers and creates visual interest when set east-west or north-south. The pear's bow-tie effect (dark area across the center) varies by cut quality—select stones with minimal visible bow-tie for optimal beauty.

Shape selection should reflect personal style, lifestyle factors (active hands may prefer lower-profile cuts), and metal choice. Contemporary unique Lab Grown Diamond rings increasingly feature fancy shapes like marquise, Asscher, and trillion cuts that differentiate from traditional round solitaires.

Diamond Certification Explained: Your Quality Guarantee

Certification from reputable gemological laboratories provides independent verification of a diamond's 4C grades. Without documentation from recognized authorities, visual estimates remain unreliable for determining quality. Never purchase a significant diamond without grading documentation.

Three laboratories dominate the certification landscape: GIA (Gemological Institute of America), IGI (International Gemological Institute), and GCAL (Gem Certification and Assurance Lab). GIA created the 4C system and maintains the strictest grading standards. IGI provides thorough evaluations widely accepted across the industry. GCAL offers consumer-focused reports with cut analysis and light performance data.

A grading report documents carat weight, cut grade, color grade, clarity grade, measurements, polish, symmetry, fluorescence, and diagrammed inclusions. GIA reports use the D-Z color scale and FL-I3 clarity scale. IGI reports provide similar grading with slightly different standards. Many reports include a plotted diagram showing the exact location of clarity characteristics—a fingerprint unique to each diamond.

Verifying certification proves essential before purchase. Every certified diamond receives a report number laser-inscribed on its girdle, invisible without magnification. Cross-reference this number against the laboratory's online database (GIA's report check at gia.edu, IGI's verification atigi.org) to confirm authenticity and review original grading details.

At StoneBridge, we exclusively offer certified Lab Grown Diamonds with documentation from GIA, IGI, or GCAL. This commitment ensures you're purchasing exactly what the grading report describes—no visual estimates, no misleading descriptions. Each stone's certification accompanies the diamond through delivery.

Sustainable and Ethical: The Hidden Value of Lab Grown Diamonds

Choosing a Lab Grown Diamond represents a statement about values. Sustainable Engagement Rings crafted from ethically produced stones address concerns that increasingly matter to modern couples planning lifetime commitments.

Environmental benefits are substantial. Diamond mining disturbs land averaging 100 square feet per carat extracted, consumes approximately 480 gallons of water per carat, and generates 125 pounds of carbon emissions. Lab production requires considerably fewer resources, with facilities like Diamond Foundry operating entirely on renewable energy. Industry sustainability reports indicate Lab Grown Diamonds produce approximately 250 times less carbon per carat compared to mined alternatives.

Ethical considerations drive many couples toward lab created options. Traditional diamond mining has historically raised human rights concerns in certain regions. Lab production occurs in controlled facilities in the US, India, and Singapore with regulated labor practices, eliminating concerns about conflict minerals or exploitative working conditions. These facilities typically employ fewer than 50 workers per growth chamber, ensuring safe working environments.

These diamonds qualify as ethical diamond jewelry by any reasonable standard. They carry none of the baggage associated with problematic supply chains. Couples can exchange rings with clear consciences, knowing their symbol of commitment doesn't inadvertently fund harm.

Certifications from organizations like the Responsible Jewellery Council and SCS Global Services provide third-party verification of sustainable practices among participating retailers. Look for recycled metal certifications (950 platinum or 14K/18K recycled gold) to maximize environmental benefits. Ask your jeweler about sourcing transparency and environmental commitments when shopping for wedding bands with Lab Grown Diamonds.

Practical Shopping Tips: Getting the Best Lab Solitaire for Your Budget

Strategic prioritization transforms your 4C knowledge into smart purchasing decisions. Use this framework to allocate budget where it matters most.

Tier 1: Cut quality demands your highest priority. An Excellent-cut diamond delivers visible brilliance no other factor can match. Never compromise cut grade for marginal improvements in color or clarity. An Excellent-cut 1ct G-VS2 outperforms a Very Good-cut 1.3ct with better color every time.

Tier 2: Color and clarity should fall within acceptable ranges—typically G-H color and VS1-VS2 clarity for optimal value in 14K white gold or platinum settings. These grades provide eye-clean appearance without premium pricing. For yellow gold settings, you can safely drop to I-color without visible warmth.

Tier 3: Carat weight represents the flexible factor. Once cut, color, and clarity meet quality thresholds, remaining budget flows toward size. A 1.5ct E-VS1 in your budget beats a 1ct D-VVS1 if both are Excellent-cut.

For different budgets, consider these starting points:

• $3,000-$5,000: 0.80-1.00 carat, Very Good-Excellent cut, H-I color, VS2-SI1 clarity—pair with 14K white gold solitaire setting
• $5,000-$8,000: 1.00-1.50 carats, Excellent cut, G-H color, VS1-VS2 clarity—consider 18K gold or platinum 4-prong setting
• $8,000-$12,000: 1.50-2.00 carats, Excellent cut, F-G color, VVS2-VS1 clarity—upgrade to 950 platinum with cathedral setting

Trusted online retailers like StoneBridge offer substantial inventory with detailed specifications and high-resolution imaging. Local jewelers provide in-person consultation and immediate gratification. Many buyers combine approaches—researching online before visiting showrooms to examine specific stones in 14K white gold or platinum settings.

Before purchase, verify your diamond checklist:

• GIA, IGI, or GCAL certification with verified report number
• Excellent or Very Good cut grade
• Acceptable color and clarity for your setting metal
• Proportions within ideal range (table 54-57%, depth 60-62.5%)
• Secure 4-prong or 6-prong setting in 14K/18K gold or 950 platinum
• Realistic warranty and return policy

Common Mistakes to Avoid When Buying Lab Grown Solitaire

Even informed buyers encounter pitfalls. Steering clear of these errors protects your investment and ensures satisfaction with your engagement ring for decades.

Prioritizing carat weight over cut quality undermines value immediately. A larger diamond with poor proportions appears lifeless compared to a smaller, precisely cut stone. A 1.5ct Good-cut diamond will look duller than a 1ct Excellent-cut stone—cut creates beauty, size alone impresses no one.

Purchasing without certification leaves you vulnerable to misrepresentation. Visual inspection cannot reliably determine color, clarity, or carat weight. Always insist on current grading documentation from GIA, IGI, or GCAL. Verify the report number matches the laser inscription on the diamond's girdle.

Confusing lab grown Diamonds vs Moissanite causes significant disappointment. While moissanite displays impressive brilliance, it ranks 9.25 on the Mohs scale (compared to diamond's perfect 10) and features distinct fire patterns with rainbow flashes visible to the naked eye. Lab Grown Diamonds match natural diamond properties exactly—refractive index of 2.42, dispersion of 0.044—moissanite does not.

Overlooking setting quality compromises even the finest diamond. The setting holds your stone securely for decades. A client came to us heartbroken six months after her engagement when her center stone—gorgeous, a 1.2ct F-VS1—work loose from cheap prongs and vanished into a parking lot drain. She hadn't thought about what happens when beauty meets reality. Insist on quality metal (14K-18K gold or 950 platinum), adequate prong thickness (at least 1.5mm for platinum, 2mm for gold), and proper workmanship.

Avoid setting metals that wear poorly with your lifestyle. Platinum suits active lifestyles better than gold due to its density (21.45 g/cm³) and superior scratch resistance, though it develops a patina over time. White gold requires periodic replating (every 12-18 months) as the rhodium layer wears. Yellow gold and rose gold require less maintenance but show wear more visibly.

Caring for Your Lab Grown Diamond Solitaire Ring

Lab Grown Diamonds demand identical care to natural stones. Proper maintenance preserves brilliance for decades of daily wear in your Engagement Ring Setting.

At-home cleaning proves straightforward. Soak your ring in warm water with mild dish soap for 15-20 minutes. Gently scrub with a soft-bristled brush—a soft toothbrush works excellently—focusing on the underside of the diamond where oils and lotions accumulate. Rinse thoroughly and dry with a lint-free cloth. Lab Grown Diamonds are safe for ultrasonic cleaners, unlike some gemstones, making professional-grade cleaning accessible at home with devices available for $30-$80.

Professional cleaning every six months maintains optimal appearance. Jewelers use ultrasonic cleaners (operating at 40kHz frequency) and steam equipment that remove buildup impossible to address at home. This service typically costs nothing at reputable jewelry stores when purchased from them.

Protect your setting through mindful wear. Remove rings before activities involving harsh chemicals (cleaning products, chlorine bleach), heavy lifting, or impact risk. Chlorine damages metal alloys, particularly affecting 14K white gold's rhodium plating. Physical blows can loosen prongs or bend shanks. Annual prong inspection (included free at most jewelers) catches potential problems before stones are lost—prongs should be checked every 6-12 months.

Safe storage matters when your ring isn't being worn. Dedicated ring boxes with individual compartments prevent scratching between pieces. Travel cases with padded interiors protect during trips. Store platinum and gold separately—different karat golds can scratch each other. Never store multiple rings loose in drawers where metal can scrape against metal. A fabric-lined jewelry tray works excellently for daily storage.

These care practices apply if you are maintaining wedding bands with Lab Grown Diamonds, anniversary rings, or your original proposal ring. That ring you'll wear every day for years—it becomes part of your story,见证 your first anniversary, your children's questions about how mom and dad met, the quiet moments and the celebrations. Consistent care ensures your symbol of commitment remains as brilliant as your relationship. Consider applying perfume, hairspray, and lotions before putting on your ring to minimize chemical exposure to both diamond and metal.

Lab Grown Diamond Trends to Watch in 2026

The Lab Grown Diamond market continues evolving rapidly, with several trends shaping purchasing decisions for engagement rings and fine jewelry.

Colored Lab Grown Diamonds are experiencing remarkable growth. Pink, blue, yellow, and green fancy colored diamonds previously required extraordinary budgets accessible only to collectors. Lab production makes these hues achievable for mainstream consumers. Pink lab diamonds particularly dominate celebrity lab grown engagement ring choices, with vivid and intense pink grades trending across social media. Blue lab diamonds with treated boron molecules achieve Fancy Deep Blue grades previously costing $100,000+ in mined stones.

Unique lab grown diamond rings increasingly feature unconventional shapes, asymmetric designs, and creative settings. Consumers seek differentiation from traditional round solitaires, gravitating toward marquise, trillion, and Asscher cuts that offer distinctive character. East-west set oval diamonds and north-south pears create modern alternatives to classic prong settings.

Halo settings incorporating smaller accent stones around central solitaires are surging. These designs maximize perceived size while offering aesthetic variety—a 1ct center stone with diamond halo appears larger than a 1.25ct solitaire alone. Lab grown diamonds make substantial center stones affordable enough to accommodate surrounding accent diamonds without exceeding budgets.

Bezel and semi-bezel settings appeal to active individuals seeking durability without sacrificing beauty. These protective designs feature metal encircling the diamond's girdle (full bezel) or partial coverage (semi-bezel), reducing impact risk while maintaining elegant appearance. Platinum bezels offer maximum protection for daily wear.

Celebrity influence continues driving trends. When high-profile couples announce engagements featuring colored or fancy-Cut Lab Diamonds, corresponding searches and purchases spike dramatically. Celebrity choices provide inspiration, though personal preference should ultimately guide your decisions. Your ring should reflect your style, not follow trends blindly.

Frequently Asked Questions

What are the most important 4Cs to prioritize when buying a lab grown diamond solitaire engagement ring?

Cut should be your top priority as it most directly affects brilliance and sparkle. For lab diamonds priced at $3,000-$8,000, you can often afford to prioritize cut quality while still getting excellent color (D-H) and clarity (VS1-VS2) grades within budget. An Excellent-cut diamond delivers visible superiority over stones with better color or clarity but inferior proportions. Focus your budget here first, then allocate remaining funds to carat weight. A 1ct Excellent-cut G-VS1 in 14K white gold outperforms a 1.2ct Very Good-cut F-VVS1.

How do Lab Grown Diamond Prices compare to natural diamonds for equivalent 4C grades?

Lab grown diamonds typically cost 30-50% less than natural diamonds with comparable specifications. A 1-carat VS1 clarity F-color round brilliant might cost $8,000-$10,000 lab grown versus $15,000-$20,000 natural. With $8,000 budget, you might secure a 1.5ct G-VS2 lab diamond versus a 0.80ct equivalent in mined form. The savings scale up significantly with larger stones—a 2ct E-VS1 lab diamond at $12,000 would cost $35,000-$45,000 mined. Budget accordingly and prioritize cut quality over size.

Are lab grown diamonds less durable than natural diamonds for everyday wear in solitaire rings?

No, lab grown diamonds have the same hardness (10 on the Mohs scale) and durability as natural diamonds. They rank among the hardest materials on Earth, making them equally suitable for everyday wear in engagement rings. Lab production creates genuine diamond material with identical structural properties—refractive index 2.42, thermal conductivity 2,200 W/m·K, and dispersion 0.044. Your ring will last a lifetime with proper care, just like a mined diamond would.

What diamond certification should I look for when purchasing a lab grown solitaire?

Look for certification from GIA (Gemological Institute of America), IGI (International Gemological Institute), or GCAL (Gem Certification and Assurance Lab). These reports verify the 4C grades and confirm the diamond is lab grown. Verify the certification number against the issuing laboratory's online database before completing your purchase. Reputable sellers like StoneBridge include this documentation with every stone and provide verification support.

How do I care for my lab grown diamond solitaire ring to Keep It Sparkling?

Clean your ring weekly with warm water and mild dish soap, using a soft toothbrush to scrub underneath the diamond where oils accumulate. Lab grown diamonds are safe for ultrasonic cleaners—unlike sapphires or emeralds—which use high-frequency sound waves (typically 40kHz) to remove debris. Professional cleaning every six months at your jeweler keeps it in top condition. Remove your ring during heavy lifting, swimming in chlorinated pools (chlorine damages 14K white gold's rhodium plating), and activities where it might get knocked. Annual prong inspections at your jeweler catch loose settings before diamonds are lost.
