What we supply
Our lab-grown diamonds are CVD (chemical vapor deposition) Type IIa — chemically, physically and optically identical to mined diamonds, graded by IGI and GIA to the same standards.
In the portal you can filter by shape, carat, color, clarity, cut, lab and measurements, open the certificate, request a stone on memo, or set it straight into a mounting.
- Cut
- How well the facets return light. For rounds it is graded Excellent to Poor; for fancy shapes, judge the proportions, symmetry and bow-tie.
- Color
- Graded D (colorless) down the alphabet. Our standard for jewelry is F-G — white face-up in any metal.
- Clarity
- Graded FL to I3 by the size and position of inclusions. Our standard is VS2 or better — eye-clean.
- Carat
- Weight, where 1 carat is 0.2 grams. Ask for measurements as well — spread matters as much as weight on fancy shapes.
