12.18 Carat Blue SRI LANKAN Cushion Sapphire AGL

This is a 12.18 carat blue sapphire of Sri Lankan origin, cut in a cushion shape and certified by AGL (American Gemological Laboratories). The stone is unheated and untreated, which is notable given its size and saturation. It is offered as a loose stone without a setting. The Sri Lankan source combined with the absence of treatment documentation makes this suitable for buyers seeking natural sapphires with documented provenance.
