This 1.01 carat round lab grown diamond, cut with 57 facets to return the most light of any shape. At D color it sits at the very top of the scale: icy and completely colorless. SI1 clarity keeps the price sensible while staying lively to the eye. Cut to ideal proportions for maximum brilliance.

It is chemically, physically and optically identical to a mined diamond, different only in origin, with none of the mining footprint.

Sold loose at 6.5 mm face-up, it is ready to become an engagement ring stone, a pendant or a one-of-one piece. Graded by IGI under report 770629305, laser-inscribed on the girdle, and shipped insured from Surat.

Is this a real diamond?

Yes. This 1.01 carat round is a lab grown diamond: chemically, physically and optically identical to a mined diamond, different only in origin. It is graded by IGI, an independent gemological laboratory.

How do I verify the certificate?

The IGI report number is 770629305. It is also laser-inscribed on the girdle of the stone. Look the number up on igi.org and match it to the inscription under a 10× loupe when the stone arrives.

How big does it look?

What do D color and SI1 clarity mean?

D color is in the colorless range, the top of the color scale. SI1 clarity means inclusions are visible under 10× magnification and usually not to the naked eye.

Can I see the real stone before I buy?

Yes. The gallery shows this exact stone in real photos and a 360° video. If you want another angle or a closer look at a detail, ask us and a partner in Surat will reply.
