Long ago sapphires, with the exception of blue sapphires, were often dubbed « oriental » and the term was used as a prefix before the color designation. Green sapphire, for example, was called « Oriental Emerald » until it was decided in the trade that the practice was misleading (and gemologically inaccurate). While the gem gravels of Sri Lanka occasionally produce very small green sapphires–the present example originates from Burma–a significantly rarer source for fancy-colored sapphires.
Of an impressively large size, this pastel green stone is a pure green sapphire from Burma, unmodified by other colors. Its color is natural and unenhanced by any heat treatment. This is not something frequently encountered in the trade. Most sapphires appear to show a blend of more than one color rather than a single pure hue. The present stone is rare for its substantial size, for its color and for its excellent luster. While one may see small green sapphires from Sri Lanka from time to time, a stone of this size and color saturation originating from Burma is a very rare commodity indeed.
