The Truth About Lab-Grown Diamonds: Are They Real Diamonds?
Share
Introduction
If you've been researching engagement rings, you've probably come across lab-grown diamonds and wondered: are they actually real? Are they just "fake" diamonds with a clever marketing spin? At Aurevyn Paris, we believe in complete transparency — so let's set the record straight once and for all.
What Is a Lab-Grown Diamond?
A lab-grown diamond is a real diamond. Full stop.
It is composed of the exact same material as a mined diamond — pure carbon arranged in a crystal structure — and is created using one of two processes:
- HPHT (High Pressure High Temperature) — replicates the natural conditions deep within the earth that form diamonds over billions of years, compressed into weeks
- CVD (Chemical Vapour Deposition) — carbon-rich gas is ionized into plasma, and carbon atoms deposit layer by layer onto a substrate, growing a diamond crystal
The result is a stone that is chemically, physically, and optically identical to a mined diamond. Even trained gemologists cannot distinguish them without specialized equipment.
Lab-Grown vs. Mined: What's Actually Different?
| Property | Lab-Grown Diamond | Mined Diamond |
|---|---|---|
| Chemical composition | Pure carbon (C) | Pure carbon (C) |
| Crystal structure | Cubic | Cubic |
| Hardness | 10/10 | 10/10 |
| Refractive index | 2.42 | 2.42 |
| Thermal conductivity | Same | Same |
| Origin | Laboratory | Earth |
| Price | 50–70% less | Premium |
| Environmental impact | Minimal | Significant |
| Ethical concerns | None | Varies |
5 Myths About Lab-Grown Diamonds — Debunked
Myth 1: “Lab-grown diamonds aren’t real diamonds.”
False. The Gemological Institute of America (GIA) — the world’s most respected diamond authority — certifies lab-grown diamonds and grades them using the exact same 4 Cs as mined diamonds. They are real diamonds by every scientific and gemological standard.
Myth 2: “Lab-grown diamonds look different.”
False. They are visually identical. No jeweller, no gemologist, and no guest at your wedding will be able to tell the difference with the naked eye.
Myth 3: “Lab-grown diamonds have no value.”
Partially true — but so do mined diamonds. The resale market for both has declined significantly. Neither is a strong financial investment. Buy a diamond because you love it, not as an asset.
Myth 4: “Lab-grown diamonds are bad for the environment.”
Compared to mining? Significantly less so. Diamond mining displaces enormous amounts of earth, consumes vast water resources, and has been linked to habitat destruction. Lab-grown diamonds require energy — but that footprint is a fraction of traditional mining.
Myth 5: “Only mined diamonds are certified.”
False. Lab-grown diamonds are certified by GIA, IGI, and other leading gemological laboratories. Aurevyn Paris provides certification documentation with every lab-grown diamond purchase.
Why Are Lab-Grown Diamonds So Much Cheaper?
It’s not because they’re inferior — it’s because the supply chain is shorter and more efficient. Mined diamonds pass through miners, exporters, cutters, wholesalers, and retailers before reaching you. Lab-grown diamonds skip most of that chain.
The result: you get the same stone for 50–70% less. That means a larger carat, a better cut, or a more intricate setting — all within the same budget.

Final Thoughts
The diamond industry spent decades convincing consumers that only earth-mined diamonds were worthy of love. Science — and the GIA — disagree. A lab-grown diamond is a real diamond in every way that matters: chemically, physically, visually, and emotionally.
