What is the difference between VVS1 and VVS2 lab-grown diamonds?

Both grades are eye-clean and nearly flawless. VVS1 has fewer and smaller inclusions than VVS2 when examined under 10x magnification, but the difference is not visible to the naked eye. VVS1 carries a price premium over VVS2 at the same carat weight.

Are these loose diamonds IGI certified?

Yes. Every stone is IGI certified to D color and Ideal 2EX cut. We email the certificate for your review before the diamond ships.

What is MISI and why does it matter?

MISI, the MadisonDia Ideal Sparkle Index, is a proprietary 0 to 100 scale that measures a diamond's real-world light performance beyond the standard 4Cs. Every stone in this collection scores 80 or higher.

Can I buy a fancy pink lab-grown diamond?

Yes. This collection includes fancy light pink diamonds in VS1 and VS2 clarity, offered alongside the standard D color range.

Can I have a ring custom-made around a loose diamond?

Yes. Choose your loose stone, then use our design service to create a custom setting, with a CAD and 3D preview before production begins.

How do I verify my diamond's IGI certificate?

Enter the report number from your certificate directly on the official IGI website at igi.org. The listed specifications should match your diamond.
