A delightful, unheated, Ceylon blue with the most awesome cut. Full brilliance, absolutely no window. It has some zoning face down, but no visible when face up. Hence the low price. This lab certified unheated, Ceylon blue hails from the gem fields of Elahera, Sri Lanka, and was cut in Ratnapura. Independently certified by the Lakshani Gem Testing Lab from Colombo, Sri Lanka as unheated. A beautiful sapphire priced well.
