A diamond, in every way that matters.
A lab-grown diamond is chemically, physically and optically identical to a mined diamond. Same hardness (10 on the Mohs scale). Same fire. Same forever. What changes is only its origin — and, quietly, almost everything else about it.
From carbon to crystal, in weeks.
A tiny diamond seed is placed inside a chamber that recreates the heat and pressure of the earth's mantle. Carbon atoms bond, layer over layer, and grow the seed into a rough diamond — atom-identical to one formed underground over a billion years.
The rough is then cut and polished by master artisans, and graded independently by IGI on the same 4Cs — Cut, Colour, Clarity, Carat — used for mined diamonds.

Not all sparkle is diamond.
Moissanite and cubic zirconia are common substitutes — inexpensive, bright, but they are not diamonds. They wear differently, fade differently, and are graded on a different scale.
| LimeLight Lab-Grown | Moissanite | Cubic Zirconia | |
|---|---|---|---|
| Composition | Pure carbon (real diamond) | Silicon carbide | Zirconium oxide |
| Hardness (Mohs) | 10 | 9.25 | 8.5 |
| Brilliance over time | Forever | Rainbow flash, dulls with wear | Fades, clouds, scratches |
| Certified as diamond | Yes — IGI | No | No |
| Resale / heirloom value | Yes | Minimal | None |
Same brilliance. Better conscience.
Ethical Origin
No mining. No conflict. Every diamond is fully traceable to its lab of origin.
Bigger, Better
Choose 30–40% more carat, or a higher clarity, for the same investment as a mined stone.
Certified Forever
Independently graded by IGI on the same 4Cs, with a laser-inscribed report number.
Kind to the Earth
A fraction of the water, land and carbon footprint of traditional mining.

Lifetime buyback, complimentary cleaning and re-polishing at our Mangalore boutique.
Forever, Truly
10/10 hardness. It will not scratch. It will not cloud. It will outlast us all.
The truth, uncomplicated.
"Lab-grown diamonds are fake."
They are diamonds. Same carbon, same crystal, same certification. Only the origin differs.
"They lose their shine."
A diamond is the hardest known natural material. Its brilliance does not fade — mined or grown.
"They're the same as moissanite."
Moissanite is a different mineral entirely. Lab-grown diamonds are the real thing.
"They have no resale value."
Certified lab-grown diamonds hold real value, and Trayi offers assured lifetime buyback.
