3.52 Ct. Spinel from Ceylon (Sri Lanka)

This 3.52 carat cushion shape blue spinel exhibits a deliberately engineered geometric faceting scheme that maximizes light play, clarity of tone, and overall brilliance, from The Natural Gemstone Company. The mixed brilliant cut combines a faceted crown with a modified brilliant pavilion, creating a precise interplay of large steplike pavilion facets and smaller brilliant crown facets, resulting in strong internal reflections and focused scintillation. The table is proportioned to balance light return and color saturation, while the girdle and facet junctions show consistent symmetry that preserves facet contrast under varied lighting. Measured at 9.29 by 6.82 by 5.70 mm, the stone demonstrates a medium color intensity in a clean blue spectrum, and the excellent polish enhances facet crispness and visual depth. Clarity is graded slightly included at eye level, with inclusions that are localized and do not materially interrupt the engineered light paths, allowing maximum fire and brilliance without visible disruption in typical viewing angles. Origin is Ceylon Sri Lanka, and the stone has no enhancement, confirming natural color and optical properties suitable for collectors and precision jewellers.

From a craftsmanship perspective the cutter has optimized pavilion angles to channel light back through the crown facets, producing a measured balance of brightness and contrast that emphasizes the spinel colors without overwhelming saturation. The mixed brilliant approach creates a geometric optical signature, with repeating rectangular and kite shaped crown facets that produce a faceted window effect when viewed face up, and parallel facet planes on the pavilion that afford a controlled flash pattern. The excellent polish and tight facet junctions support strong specular highlights, and the slightly included clarity grade permits a natural appearance while maintaining technical integrity for fine mounting. For pairings and design notes, the listed opal type, White Opal, complements this blue spinel by offering diffuse play of color and soft background contrast against the spinel geometric brilliance, making combined settings attractive for bespoke pieces. This gem is presentation ready for ring or pendant designs that require precise setting and light control, and our team at The Natural Gemstone Company can advise on bezel or low profile prong settings to preserve the engineered light paths and protect the pavilion depth while showcasing the optimized geometric faceting.
