Yes. Moissanite is a genuine gemstone — silicon carbide, one of the hardest minerals on earth. It’s a certified stone in its own right, never glass or cubic zirconia.

Beautiful, and on its own terms. Set in a ring, moissanite is brilliantly clear and white, with a lively fire all its own — the flashes of rainbow color a stone gives off when it catches the light. To the eye it simply reads as a stunning gemstone.

Every Sempre piece is made to the same fine standard — the same metal, setting, and craftsmanship as any fine jewelry. Because moissanite is created in a laboratory rather than mined, the price reflects the stone itself, never a compromise on quality.
