Loose Moissanite Stones

Explore loose moissanite stones for custom rings, jewelry projects and replacement requests. Browse the collection for different cuts, shapes and colors, then review the actual millimeter measurements and available stone options on each listing. Moissanite is a separate gemstone from diamond.

Stone measurements matter when choosing a setting. Confirm the length, width and depth your design requires, and discuss compatibility with your jeweler before ordering a loose stone. Where a listing uses a diamond-equivalent carat size, refer to the millimeter dimensions for the fit.
