Burmese sapphires can command some of the highest prices on the sapphire market. Color is the single most influential quality factor affecting the value of a sapphire. Due to trace elements iron and titanium, Burma’s deposits produce sapphires of rich and intense hue, which stones from other sources are judged against.

This sapphire is one of the most extraordinary examples of such quality. Remarkably, the stone has not gone through any heat treatment to enhance its color and clarity, a quality that marks its rareness and extremely high market value, stranding out from all its peers.
