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.

What GRA certification means for moissanite

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 — it is a moissanite grading card, not a diamond grading report like IGI or GIA. At GemHub & Co., every moissanite ring ships with its original GRA certificate so you know exactly what you own.

How does moissanite sparkle compare to a diamond of the same size?

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.

Size guide

Most GEMHUB & CO. rings ship in US size 7. Custom sizing is available on request – email [email protected] and we will confirm before crafting.

Use a ring that fits the desired finger.
Measure the internal diameter of the ring in millimetres. Make sure your ruler starts at the 0 mm mark.

Between two sizes? Choose the larger one for comfort. Wider bands usually need a slightly larger size.
