This is a 1.00 carat (6.5mm) round brilliant moissanite, precision-cut and graded D colour, VVS1 clarity — top-tier quality with exceptional optical performance. Moissanite is a lab-grown gemstone known for its unique optical properties. Unlike Diamond, it is doubly refractive, meaning it splits light into two rays. This creates the distinctive facet doubling / “hall of mirrors” effect, giving the stone a deeper, more dynamic sparkle under light. Key characteristics Strong fire & brilliance (higher refractive index than diamond) Near-diamond hardness (9.25 Mohs) — suitable for everyday wear Ethically produced — 100% lab-grown, no mining Excellent value compared to diamond In person, the stone shows: Intense sparkle and light return Sharp, well-defined facet structure Noticeable optical depth from double refraction Included GRA certificate + report number GemDrop verification ID (linked to online database record) Lifetime warranty card Protective presentation case GemDrop verification Each stone is individually recorded in the GemDrop database and can be verified online. The record matches your exact stone specifications (size, cut, quality), providing a transparent and traceable reference. Suitable for Rings, earrings, pendants, or custom projects Buyers who appreciate strong fire and optical performance Anyone looking for a high-quality alternative to diamond Condition: Flawless / unused UK-based seller. Fast dispatch.

Lot of 19 premium loose moissanite gems totaling 44+ carats. Mostly round brilliant cut with a few fancy shapes, in a range of colors: white, off-white, blue, green, gray, and amber. All gems are excellent cut and clarity, authentic (see photo), and were purchased for personal jewelry projects that never came to fruition. Priced well below what you’d pay sourcing these individually. At current market rates for high-quality moissanite per carat, this lot is a strong value that’s ideal for a jeweler, custom designer, or reseller looking to move them individually.
