Our lab grown diamonds 1 carat and above come with an IGI report, an independent grading certificate from the International Gemological Institute, one of the world's major diamond labs. We use IGI as our certification standard.

A lab grown diamond is a diamond. Same crystallized carbon, same 10-on-the-Mohs-scale hardness, same fire, same way it passes a diamond tester. The only difference is origin: ours are created in a controlled facility rather than mined from the earth. That's it. It's not a simulant, not an imitation. (Cubic zirconia and moissanite are different materials; a lab grown diamond is the real thing.)

Yes. A lab grown diamond is a diamond: pure crystallized carbon, graded on the same 4Cs (cut, color, clarity, carat) by the same labs. It is not a simulant. Cubic zirconia and moissanite are different materials that imitate the look of diamond; a lab grown diamond is diamond. The U.S. Federal Trade Commission requires sellers to disclose that a stone is lab grown, which is why you'll see "lab grown," "lab-created," or "laboratory-grown" on honest listings, including ours.

Shape is personal and it drives everything else. Rounds sparkle the most; ovals and pears look larger for their weight; emerald and asscher cuts are clean and architectural; cushions and old mine cuts feel soft and vintage.
