This 4.629 ct natural spinel from Ceylon (Sri Lanka) displays a saturated purplish red, the most coveted hue in the spinel family. Cushion-cut to ideal proportions (10.02 × 7.97 × 6.40 mm), it earns Bellerophon's "Vibrant" designation for its precision return of light. The stone is internally flawless — a rare distinction — with medium fluorescence adding to its inner glow, and shows no indications of any treatment. Formed roughly 550 million years ago in the gem gravels of Sri Lanka, it is accompanied by Bellerophon Gemlab report C01438.
