A natural Ceylon sapphire of vivid blue, the saturated tone the trade calls royal blue. The 3.681 ct cushion is evenly coloured and transparent, with stable colour.
This stone has been heated. Bellerophon Gemlab records indications of heating and notes no other treatment. Heating is the long-established, permanent treatment used on most sapphire; we state it plainly so that the price reflects it.
Mined at Téja's own pit at Horaketiya, Ratnapura, Sri Lanka, and cut in Sri Lanka.
