Well, here is a blue sapphire with excellent color that might have been only gently heated. Hailing from the gem fields of Balangoda, it is cut & polished by our Ratnapura cutter. Marvelous, super-cutting, as clean as it gets, and good ring size, this blue sapphire exudes perfection from every angle. It is an excellent medium-dark Ceylon blue at a meager price. Low heated only, no other treatments.
