Round Moissanite Rings
The round brilliant is the classic engagement ring shape. Its facets are arranged to return as much light as possible, and moissanite, with a refractive index of 2.65 and a dispersion of 0.104, adds strong rainbow fire on top. It works in any setting, from a plain solitaire to a halo or a full eternity band.
Round stones also make the easiest bands to match. Set a round eternity band beside a round solitaire for a matched look, or browse our wedding and stacking bands. New to moissanite?
