What Are Lab-Grown Diamonds?
Real diamonds, grown by science rather than mined from the earth - identical in every way to natural stones, only kinder to the planet and to your budget.
Explore The CollectionA Diamond, Simply Grown Differently
The same carbon, the same fire, the same forever - created in a lab instead of a mine.
A lab-grown diamond is not an imitation and not a substitute. It is a genuine diamond with the same chemical, physical, and optical properties as a mined stone - graded on the very same scale by the very same laboratories. The only difference is its origin.
Yes - They Are Real Diamonds
This is the question we hear most, so let us be clear. A lab-grown diamond is a diamond. It is not glass, not crystal, not a look-alike. It is pure crystallised carbon, indistinguishable from a stone pulled out of the earth.
The distinction lives in a single word: origin. One grows underground over an unimaginable span of time; the other grows in a matter of weeks inside a controlled laboratory. Both are, in every sense that matters when you wear one, the real thing.
Two Methods, One Brilliant Result
Every lab-grown diamond begins with a tiny diamond seed and nature's own recipe of carbon, pressure, and heat.
HPHT
High Pressure, High Temperature. A diamond seed is surrounded by pure carbon and exposed to pressures above 1.5 million pounds per square inch at temperatures near 1,500°C - mirroring the forces deep in the earth's mantle. The carbon crystallises onto the seed, growing a rough diamond.
CVD
Chemical Vapour Deposition. A seed is placed in a sealed chamber filled with carbon-rich gas. The gas is heated until carbon atoms break free and settle onto the seed layer by layer - building the diamond upward like frost forming on glass.
Once grown, each rough stone is cut and polished by master craftspeople using exactly the same techniques applied to natural diamonds.
Identical Where It Counts
Same composition, same brilliance, same lasting hardness - a different origin and a different price.
| Property | Lab-Grown | Natural |
|---|---|---|
| Composition | Pure crystallised carbon | Pure crystallised carbon |
| Hardness | 10 on the Mohs scale | 10 on the Mohs scale |
| Brilliance & fire | Identical sparkle and light return | Identical sparkle and light return |
| Graded by the 4Cs | Yes - by the same labs | Yes - by the same labs |
| Origin | Grown in weeks in a lab | Formed over billions of years |
| Value | Typically 30–50% less for a comparable stone | Higher, tied to rarity of supply |
Beauty With A Clear Conscience
Exceptional Value
Grown rather than mined, they cost far less than natural stones of equal quality - a larger, finer diamond for the same budget.
Ethically Created
Every stone is traceable and conflict-free by nature - a transparent, controlled process from seed to sparkle.
Kinder To Earth
Growing a diamond disturbs no land and displaces no earth - a lighter-footprint choice for the conscious buyer.
Certified Quality
The same hardness, the same fire, the same certified 4C grading. Every stone arrives with proof.
Every Shinewine diamond is certified and traceable - because a diamond you wear for a lifetime should come with proof, not promises.
Thoughtfully Crafted, Endlessly Worn
Every Shinewine piece is set with certified lab-grown diamonds and crafted in fine gold. Each design is made to be worn every day and treasured for a lifetime - from a first solitaire to a milestone gift.
It is fine jewellery made honestly: brilliant, responsibly created, and always accompanied by certification. Everyday luxury, redefined.
Good To Know
Yes. Because it is chemically identical to a mined diamond, it passes a standard diamond tester as a genuine diamond - because that is exactly what it is.
Absolutely. They score a perfect 10 on the Mohs hardness scale, the same as natural diamonds, making them ideal for everyday wear over a lifetime.
No. The lower price reflects a shorter, more efficient supply chain - not lesser quality. A lab-grown diamond can match or exceed a natural one on every one of the 4Cs.
Yes. Every stone is certified and traceable, so you always know exactly what you are wearing. Every stone arrives with proof.
