6.7ct DEW White Moissanite Round Solitaire Ring

Over six carats of round brilliant brilliance — the 6.7ct DEW White Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. The round brilliant cut is the world's most popular gemstone cut — optimised over a century for maximum light return, and at 6.7ct DEW, every facet performs at full scale.

Why is round brilliant the most popular cut for solitaire rings?

The round brilliant cut was mathematically optimised in 1919 by Marcel Tolkowsky, who calculated the exact proportions needed to maximise internal light reflection in a diamond. With 57 or 58 precisely angled facets, the round brilliant is the most scientifically engineered cut in fine jewelry. It returns more light to the eye than any other shape, producing the bright "white" return and coloured fire that defines the classic diamond look. For moissanite — which has even higher refractive index than diamond — the round brilliant is particularly effective, squeezing maximum performance from the stone's optical properties.

Does GEMHUB offer resizing for large moissanite rings?

GEMHUB rings are available in UK standard sizes, and our customer team can advise on sizing before purchase. For large solitaire stones above 5ct DEW, correct sizing before purchase is important — resizing is possible but more complex with large stones as the setting must remain balanced. We recommend measuring your ring size carefully or contacting our team for a sizing guide before ordering.
