FAQs

Round brilliant cut moissanite is the most popular engagement ring shape for its unmatched sparkle. With 57-58 precisely arranged facets, the round cut maximizes light return—producing the highest brilliance and fire of any moissanite shape. Round moissanite also offers the most versatile setting options, fitting virtually any engagement ring style from solitaire to halo to three-stone designs.
Round moissanite closely resembles a round brilliant diamond to the naked eye, exhibiting even more fire (rainbow flashes). Moissanite has a refractive index of 2.65-2.69 vs diamond's 2.42, producing 15-20% more brilliance. At a fraction of the cost, round moissanite engagement rings offer the look of a luxury diamond with superior sparkle and ethically sourced, conflict-free materials.
Round moissanite accommodates virtually every setting style. Classic solitaire settings showcase its brilliant facet pattern. Halo settings amplify the visual size dramatically. Three-stone settings with round side stones create a timeless bridal look. Cathedral settings add elegance while securing the head. For modern brides, East-West and tension settings offer contemporary appeal. Each setting complements round moissanite's versatile brilliance.
The most popular sizes are 1 carat (6.5mm), 1.5 carat (7.4mm), and 2 carat (8.1mm). A 1-carat round moissanite provides classic elegance ideal for daily wear. 1.5 carat offers noticeable presence while remaining practical. 2-carat round moissanite makes a dramatic statement at a fraction of diamond pricing. Consider your finger size—slimmer fingers often suit 1-1.5 carat, while larger fingers benefit from 2-3 carat.
