Ten carats of deep blue architectural brilliance — the 10.4ct DEW Blue Moissanite Emerald Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. At 10.4ct DEW in the emerald cut, this is one of the largest blue stone rings available commercially in the world. The emerald cut's characteristic step facets concentrate and deepen the blue body colour across a stone surface of approximately 16.5×12mm — creating an experience that has no natural equivalent at any price.
Blue stones at 10ct and above in the emerald cut represent the rarest category in fine jewelry. The most famous blue stones of this scale include the Hope Diamond (45.5ct cushion, deep blue), the Blue Moon of Josephine (12.03ct cushion, Fancy Vivid Blue — sold for $48.5M in 2015), and a small number of Sri Lankan sapphires in museum collections. These stones are not commercial products — they are historical artifacts. A 10.4ct blue emerald cut moissanite does not replicate these stones; it creates an entirely different category: a vivid, eye-clean, precisely cut blue stone of extraordinary scale that is commercially accessible and can be held, worn, and experienced by its owner.
Among all cut types, the emerald cut produces the most concentrated, saturated blue appearance in a blue moissanite. The step cut's large, deep pavilion facets hold the colour through the stone's depth rather than scattering it. In a round brilliant at 10ct, the blue would appear vivid but distributed across 57 small, animated facets. In an emerald cut at 10.4ct, the blue concentrates in fewer, larger facets — creating deep, slow colour shifts across wide surfaces. The result is a richer, more saturated visual blue than the same stone in a brilliant cut. For buyers who want maximum colour impact, the emerald cut is the optimal choice for blue moissanite.
