The Complete Comparison & Guide
Are lab-grown diamonds real diamonds?
Direct Answer: Yes — lab-grown diamonds are 100% real diamonds. They are chemically, physically, and optically identical to natural diamonds. The only difference is origin.
- Same carbon crystal structure (cubic crystalline carbon)
- Same hardness: 10/10 on the Mohs scale
- Same refractive index, brilliance, and fire
- Certified by IGI and GIA using the same 4Cs framework as natural diamonds
- The FTC recognizes lab-grown diamonds as real diamonds
What is the difference between lab-grown and natural diamonds?
Direct Answer: The only difference is origin. Natural diamonds form underground over billions of years; lab-grown diamonds are created in a laboratory in weeks using CVD or HPHT technology. Both are real diamonds.
- Origin: Natural = Earth-formed over 1–3 billion years; Lab-grown = created in weeks
- Composition: Identical — both are pure carbon crystal
- Price: Lab-grown diamonds cost 50–80% less than comparable natural diamonds
- Certification: Both certified by IGI and GIA using the same 4Cs grading
- Resale: Natural diamonds have a stronger resale market

Which is better: lab-grown or natural diamonds?
Direct Answer: Neither is objectively better — the right choice depends on your priorities. Lab-grown is better for value and size; natural is better for rarity and resale.
- Choose lab-grown if: You want maximum size and quality within your budget, prioritize ethics, or don't plan to resell
- Choose natural if: Geological rarity matters to you, or long-term resale value is a priority
- Both are real diamonds — the decision is personal, not qualitative
Are lab-grown diamonds cheaper? Why?
Direct Answer: Yes — lab-grown diamonds cost 50–80% less than natural diamonds of the same quality. The lower price reflects their origin, not their quality — the diamond itself is identical.
- No mining, land rights, or extraction costs required
- Scalable production drives prices down as technology improves
- A 1.00ct lab-grown diamond (G, VS1, Excellent cut) costs a fraction of the equivalent natural stone
- Lower price = larger, higher-quality diamond within the same budget
Do lab-grown diamonds look different from natural diamonds?
Direct Answer: No — lab-grown and natural diamonds are visually indistinguishable to the naked eye, to jewelers, and to standard diamond testers. Only advanced spectroscopic equipment can tell them apart.
- Identical brilliance, fire, and scintillation
- Same color and clarity grading scale
- A gemologist cannot distinguish them without specialized equipment
- IGI certificates clearly state whether a diamond is lab-grown or natural
Which certification is best for lab-grown diamonds?
Direct Answer: IGI (International Gemological Institute) is the industry standard for lab-grown diamond certification. All DEEVE lab-grown diamonds are IGI-certified.
- IGI: largest volume of lab-grown grading globally, consistent and detailed reports
- GIA: strongest for natural diamonds; also certifies lab-grown
- Always verify the certificate at igi.org or gia.edu before purchasing

Do lab-grown diamonds hold their value?
Direct Answer: Lab-grown diamonds do not hold value as well as natural diamonds. Lab-grown diamond prices have dropped 50–80% over the past decade as production scales. Buy for beauty, not investment.
- Natural diamonds: finite supply supports stronger long-term value retention
- Lab-grown diamonds: prices continue to fall as production technology scales
- The value of a lab-grown diamond is in the purchase price — not future resale
Are lab-grown diamonds ethical?
Direct Answer: Yes — lab-grown diamonds have a transparent, traceable supply chain with no mining impact. They are the most ethical choice for buyers concerned about environmental and social impact.
- No mining — eliminates land disruption, water use, and community displacement
- Fully traceable origin — no conflict diamond risk
- Lower carbon footprint than mined diamonds (especially with renewable energy production)
