Color Change Sapphire – Natural, Faceted, Brown, 1.31 ct

This Songea sapphire is a bit of a bi-color and has a moderate to strong color change from an olive green or blue green under daylight LED bulbs to a very nice purple under incandescent light. In cloudy daylight it's a lightly brownish purple color. I will check it today to see how it looks under fluorescent light, where I suspect it will turn a fairly nice blue-green color.
