A magnificent natural cobalt blue spinel from Sri Lanka, weighing 2.59 carats in a cushion cut. This extraordinary stone displays the deep, intense blue that places it among the most prized gemstones in the world — rich, saturated and luminous, with a depth of colour that draws the eye into its heart and refuses to let go.
Completely unheated and unenhanced, this spinel’s spectacular colour is driven by natural cobalt — the same element responsible for the most valuable blue spinels on earth. At VS clarity and 2.59 carats, this is a collector and investment grade stone of the highest order.

What Makes It Special
• Cobalt Spinel — Natural cobalt-driven blue is the most valuable and sought-after colour in spinel, with prices that rival and exceed fine sapphire at comparable quality
• 2.59 carats — Fine cobalt blue spinels above 2 carats are exceptionally rare; the vast majority of gem-quality examples are well under 1 carat
• VS clarity — Exceptional transparency for a natural unheated cobalt spinel of this size; most examples at this weight carry more inclusions
• Completely unheated — Natural cobalt colour of this intensity without any treatment is as pure as it gets in the gemstone world
• Ceylon provenance — Sri Lanka is one of only a handful of origins producing true cobalt blue spinel, alongside Myanmar and Tanzania
• Investment grade — Unheated Ceylon Cobalt Spinels above 2 carats represent one of the strongest and fastest appreciating value propositions in coloured gemstones today
