Lab Grown vs Natural Diamonds: Features, Benefits and Ethics
Lab grown and natural diamonds share identical features — same hardness, brilliance and 4Cs grading. The benefits diverge on price (lab grown is 60–80% less) and footprint (far less land and water), while ethics favor lab grown’s traceable origin. Natural diamonds keep an edge on resale and rarity. Rêve Diamonds certifies both with GIA or IGI reports.
Choosing between lab grown and natural diamonds is less about quality — they are the same gemstone — and more about which benefits matter to you. Breaking it down by features, benefits and ethics makes the decision straightforward.
Features: Identical by Design
Both are pure crystallized carbon, rated 10 on the Mohs scale, with the same refractive brilliance and fire. Both are graded on cut, color, clarity and carat. A lab grown diamond is not an imitation — it is a diamond, verified by the same laboratories as any mined stone.
Benefits: Where They Differ
Value
Lab grown’s biggest benefit is price. The same look for 60–80% less means a larger or cleaner stone for your budget — a 2 carat lab grown center can cost less than a 1 carat mined one. Compare by carat in our price comparison.
Choice
That value unlocks options — upgrade the setting, add matching pieces, or choose a fancier cut. Explore lab grown engagement rings and coordinating wedding bands to see how far the saving goes.
Ethical Considerations
Lab grown diamonds carry a documented origin and sidestep the sourcing uncertainty and land disruption associated with parts of the mined trade, generally using less water per carat too. Responsibly mined diamonds do exist and support many livelihoods, but provenance is harder to guarantee end to end. For buyers who prioritize transparency, lab grown offers peace of mind.
What Natural Diamonds Still Offer
Natural diamonds hold resale value more reliably and carry the romance of geological rarity. If you view your diamond partly as an heirloom store of value, that remains a genuine point in their favor.
Making Your Decision
Rank your priorities: value and footprint point to lab grown; rarity and resale point to natural. Read our diamond education guides and our beginner’s guide to lab grown diamonds before you choose.
Frequently Asked Questions

They offer clearer traceability and a lighter environmental footprint, which many buyers consider more ethical. Responsibly sourced natural diamonds are also available if you prefer mined.
Do lab grown and natural diamonds look different?
No. They are optically identical and indistinguishable to the eye; only laboratory equipment can tell them apart.
