    Common Questions

    Things buyers ask.

    Yes. Chemically, physically, and optically identical to a mined diamond. The only difference is origin — Sula's stones are grown above ground over weeks rather than mined over millennia. Both score ten on the Mohs hardness scale; both refract light identically. IGI grades them on the same criteria as mined diamonds.
