3.10 ct Red Spinel – Vivid Cushion-Cut Loose Gemstone

A striking 3.10 carat red spinel featuring a rich, vivid red colour with lively pinkish-red flashes under light. This gemstone has an elegant elongated cushion cut, combining the softness of rounded corners with the refined outline of a rectangular shape.

Its bold saturation, bright return of light and substantial size make it an impressive centre stone for bespoke jewellery. Whether chosen for a statement ring, pendant or a collector’s gemstone portfolio, this spinel offers exceptional visual impact.

Why This 3.10 ct Red Spinel Stands Out

This red spinel offers the kind of strong, attention-grabbing colour that collectors and jewellery lovers seek in a fine loose gemstone. The tone appears bright and lively rather than overly dark, allowing the faceting to reflect light cleanly across the surface.

Its elongated cushion shape also gives it a refined look that works beautifully in both classic and modern jewellery designs. At 3.10 carats, it has excellent finger coverage and visual presence, making it especially suitable for a custom ring or pendant.

Ideal For

• Bespoke engagement rings
• Statement rings
• Fine jewellery pendants
• Anniversary jewellery
• Collector gemstone holdings
• One-of-a-kind custom jewellery
• Luxury gift pieces
