Nearly ten carats of pure round brilliant moissanite — the 9.8ct DEW White Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. At this extraordinary size, the round brilliant's 57 facets operate at full scale — producing intense white brilliance and vivid rainbow fire visible from significant distance.
At large sizes, moissanite's superior optical properties become even more apparent. Moissanite's refractive index (2.65–2.69) exceeds diamond (2.42), meaning more light is reflected back to the eye. Its dispersion (0.104) is more than double that of diamond (0.044), producing significantly more rainbow fire. In a stone approaching 10ct DEW, these differences are highly visible — moissanite at this size produces a light show that natural diamonds at equivalent carat weight simply cannot match. For buyers who prioritise visual impact, this is the stone's strongest argument.
A ring of this scale requires a few practical considerations. First: finger size matters more at large stone sizes — the stone should sit balanced and proportionate to your hand. Second: everyday wear at this scale can attract attention, so consider your lifestyle and occasions. Third: for high-value purchases, check that the piece can be added to your home or personal jewelry insurance policy. GemHub & Co.'s GRA certificate provides the documentation you'll need for insurance purposes.
