Ten and a half carats of deep ocean blue — the 10.5ct DEW Blue Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. Blue moissanite at 10.5ct DEW in round brilliant cut is one of the most visually extraordinary coloured stone rings available anywhere. There is no natural blue gemstone — diamond, sapphire, or otherwise — that delivers this combination of colour, size, and optical performance at any accessible price point.
Blue diamonds (fancy blue) are among the rarest and most expensive gemstones in the world — the Oppenheimer Blue diamond (14.62ct) sold for $57.5 million at Christie's in 2016. A 10ct natural blue diamond would be priced in the tens of millions of dollars and essentially never appears in retail jewelry. Blue moissanite at 10.5ct DEW delivers deep, vivid blue colour in a round brilliant at extraordinary size — the optical performance (fire, brilliance) actually exceeds natural blue diamond's due to moissanite's higher refractive index and dispersion. For anyone who wants a large deep-blue ring, this is the only option that exists as a commercial product.
The colour treatment in blue moissanite is applied at the material level and is highly stable under normal wear conditions. It is not a surface coating — the blue colour penetrates the crystal structure. Under normal temperature ranges and UV exposure associated with everyday wear, the colour is permanent and will not fade, shift, or degrade over time. The stone will look the same in decades as it does today, with standard cleaning to remove surface deposits.
