Very amiable, lab-certified, unheated, Ceylon blue sapphire, mined in Marapana, cut & polished in Ratnapura, Sri Lanka. Classic cornflower color and a lovely cushion shape, as clean as it gets, with a soft yet dcisive energy. It is an excellent price for a no-heat Ceylon blue of this quality. Just beautiful. It is certified unheated by the GGTL (Global Gem Testing Laboratory, Sri Lanka).
