Large Moissanite Engagement Rings

Large moissanite rings with 3 carats total weight and up, from 3 CT solitaires to dramatic 5 to 16 carat statement rings. Moissanite is very hard (9.25 on the Mohs scale) and has more fire than diamond, so a big center stone stays bright and costs a fraction of a diamond of the same size. Choose halo, hidden halo, three stone, solitaire and bridal set styles, many with natural or lab-grown diamond side stones, all in solid 14K white, yellow or rose gold. Free shipping in the US and Canada.

How big does a 3, 4 or 5 carat moissanite look, and what's the difference between CT and CTW? Read our large moissanite rings guide, compare moissanite vs. lab-grown diamond, or see all moissanite engagement rings.
