Twenty-seven carats. Round brilliant. The absolute maximum. — the 27.0ct DEW White Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. A 27ct round brilliant moissanite is the largest round stone in GemHub & Co.'s collection — and one of the largest round brilliant moissanite rings available commercially anywhere in the world.
A 27.0ct DEW round brilliant moissanite has a diameter of approximately 25mm — the same width as a US quarter coin. Set in a ring, this stone extends significantly beyond the width of any finger. The 57 or 58 brilliant facets across 25mm of surface area produce a light show of genuinely extraordinary scale — every movement of the hand creates new patterns of white brilliance and coloured fire across the entire stone. There is nothing in commercial jewelry that produces more light performance than a 27ct round brilliant moissanite. It is, by any measure, the most optically powerful ring a person can wear.
This ring is for exactly one type of person: someone who wants the most. Not the most of any specific thing — the most in total. Maximum size. Maximum sparkle. Maximum presence. Maximum statement. This person has considered every option, understands completely what they are purchasing, and has decided that this is the ring they want. They may be a performer for whom a ring needs to be visible at 30 metres. They may be a collector who owns the complete size spectrum. They may simply be someone who refuses to be constrained by convention. Whoever they are, this ring was made for them.
