Over six carats of white brilliant fire — the 6.6ct DEW White Moissanite Round Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. At 6.6ct DEW, the round brilliant moissanite sits at approximately 12mm in diameter — a genuinely commanding presence for any occasion.
Moissanite is lab-created silicon carbide — no mining, no land disruption, no geological extraction required. The primary environmental input is energy for the laboratory growth process. In contrast, diamond mining requires significant land displacement, water use, and carbon footprint associated with extraction and transportation. For environmentally conscious buyers, moissanite represents a clear advantage: equivalent optical performance to diamond with dramatically lower ecological impact. Many buyers specifically choose moissanite for this reason alongside its value proposition.
From a durability standpoint, yes — moissanite at 9.25–9.5 Mohs hardness is the second hardest gemstone material and will withstand daily wear without scratching. The practical consideration at this size is lifestyle. The stone's profile (height above the finger) and width may catch on fine fabrics, and very physical work (gym, gardening, manual labour) creates impact risk regardless of stone hardness. Many buyers with large solitaires have a daily ring and reserve the statement piece for occasions — an entirely sensible approach.
