Six carats of round brilliant precision — the 6.35ct DEW White Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. A 6.35ct round moissanite delivers approximately 12mm diameter — placing it firmly in statement territory while maintaining the round brilliant's unmatched optical performance.
Moissanite scores 9.25–9.5 on the Mohs hardness scale, making it the second hardest gemstone used in jewelry after diamond (10). In practical terms, moissanite is scratch-resistant for everyday wear — it will not scratch from contact with most everyday surfaces, metals, or other gemstones softer than itself. For a ring worn daily, this durability is essential. Unlike softer stones (sapphire: 9, emerald: 7.5–8, opal: 5.5–6.5), moissanite maintains its polish and facet definition over decades of regular wear.
For solitaire rings, sizing accuracy is important — the ring should fit comfortably without spinning (which causes the stone to tilt sideways) but not so tight that removal is difficult. Fingers swell slightly in warm weather and after physical activity. The standard recommendation is to measure ring size in the evening when fingers are at their largest. GemHub & Co. rings are available across a full size range — contact our team if you're between sizes for guidance on whether to size up or down.
