Lab-grown diamonds
The same diamond. A different origin.
A lab-grown diamond is a real diamond: the same carbon, the same crystal structure, the same hardness, the same way it throws light. What differs is where it formed — in a laboratory rather than a mine — and the price, which is why the stone you can afford is usually a larger one.
How it is grown
Lab diamonds are grown by one of two methods: CVD, where carbon is deposited layer by layer onto a diamond seed, and HPHT, which recreates the pressure and heat deep in the earth. Both produce diamond, not a simulant like moissanite or cubic zirconia. We choose each stone on its grade, not on its method.
Graded like any diamond
Every stone is graded by an independent laboratory — IGI or GIA — and comes with its certificate, so the four Cs are written down rather than described.
- Cut — how well the stone returns light; the biggest single factor in sparkle.
- Color — graded from D, completely colorless, downward.
- Clarity — tiny inner features, from Flawless down; VVS and VS stones look clean to the eye.
- Carat — weight, not size: one carat is 0.2 grams.
Can you tell the difference?
Not by eye, and not with a jeweler's loupe. Only laboratory equipment can identify the origin, which is why the certificate states it.
Honest about value
A lab-grown diamond is bought to be worn, not as an investment — its price follows production costs, not mining scarcity. What you get is a larger, better-graded stone for the same budget.
