This 2.509 ct natural cobalt spinel from Ceylon (Sri Lanka) glows with a vivid violetish blue — the prized cobalt-bearing variety that ranks among the most sought-after spinels in the world. The colour is evenly distributed and stable, cut as a faceted cushion (8.80 × 7.28 × 4.32 mm) to ideal proportions that earn Bellerophon's "Vibrant" designation. Transparent and untreated, showing no indications of any treatment, it formed roughly 550 million years ago in the gem gravels of Sri Lanka. Accompanied by Bellerophon Gemlab report C02092.
