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.
Thirteen carats of deep blue fire in a pillow silhouette — the 13.3ct DEW Blue Moissanite Cushion Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified.
The cushion cut at 13.3ct DEW combines the brilliant-cut’s light performance with a softened, rounded-corner square shape — and in deep blue moissanite, the result is one of the most visually extraordinary pieces in the collection.
What is a cushion cut and how does it differ from a round or princess?
The cushion cut is a square or rectangular shape with rounded corners — like a pillow, hence the name. It was one of the most popular diamond cuts through the 18th and 19th centuries (the “old mine cut”) and has experienced a major revival in contemporary jewelry. Unlike the round brilliant, which is optimised purely for sparkle through precise mathematical proportions, or the princess cut, which has sharp corners and a more modern geometric feel, the cushion cut has a softer, more romantic character while retaining strong brilliance. At 13.3ct DEW, the cushion cut creates a stone approximately 16×16mm — an imposing square presence with softened, organic corners.
Does blue moissanite look different in a cushion cut versus an emerald or round?
Yes, distinctly. In a cushion cut, the blue colour appears in animated, scattered flashes across the facets — the brilliant-cut facets scatter the colour similar to a round cut but with the characteristic “crushed ice” or “chunky” sparkle pattern of cushion cuts. In an emerald cut, the blue is concentrated and saturated — deep and calm. In a round brilliant, it is vivid and animated. The cushion produces something between these: warmer, more romantic in character than the emerald, more geometric and deliberate than the round. For deep blue moissanite at 13.3ct, the cushion creates a particularly rich visual experience.
