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.
The largest emerald cut in the collection.
The largest step-cut moissanite ring available anywhere. — the 27.5ct DEW White Moissanite Emerald Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. At 27.5ct DEW, this emerald cut stone measures approximately 29×21mm — the width of a US dollar bill is 66mm; this stone spans nearly half of it. There is no commercial ring product in the world that exceeds this.
What are the actual dimensions of a 27.5ct emerald cut moissanite?
A 27.5ct DEW emerald cut moissanite measures approximately 29×21mm — a stone surface that is literally larger than the face of most wristwatches. Worn on a hand, this stone extends visibly beyond the finger on all sides, creating a presence that is closer to fine jewelry sculpture than conventional ring design. The step facets, at this scale, become large architectural surfaces — each one individually visible, each one reflecting its own plane of white light. At 27.5ct in the emerald cut, this ring is not worn to be noticed. It is worn to be the only thing anyone notices.
Is there a precedent for a 27ct emerald cut ring in fine jewelry history?
The largest publicly known emerald cut diamonds worn as rings are in the 30–40ct range — pieces belonging to royalty, museum collections, and a small number of billionaire private collectors. Beyoncé’s famous 18ct emerald cut ring — considered one of the most significant celebrity engagement rings in history — is smaller than this stone. At 27.5ct DEW, this moissanite ring occupies territory that, in natural diamonds, is reserved for the most extraordinary, irreplaceable objects in the history of human jewelry making. This ring delivers that visual scale as a commercial product.
