Please note: This piece is set with moissanite — a silicon carbide gemstone with its own GRA certificate. It is not a natural diamond and not a lab-grown diamond.
An exceptional ring for an exceptional moment — the 6.70ct DEW White Moissanite Round Solitaire Ring in 18K gold vermeil over 925 sterling silver. GRA certified. 6.70ct DEW gives you a stone diameter of approximately 12mm — conspicuously beautiful and impossible to miss.
GRA (Gemological Research Association) is the leading independent certification body for moissanite. A GRA certificate documents the stone's authenticity, carat weight, cut grade, colour, and clarity — the equivalent of an IGI or GIA certificate for diamonds. At GemHub & Co., every moissanite ring ships with its original GRA certificate so you know exactly what you own.
Moissanite has a higher refractive index (2.65–2.69) than diamond (2.42) and a higher dispersion (fire) index (0.104 vs 0.044). In practice, this means moissanite produces more rainbow-coloured light flashes (fire) than diamond. Some people prefer this; others prefer diamond's subtler sparkle. In photos and video, moissanite is exceptionally photogenic.
