Corundum (color change sapphire) - Sold

Corundum ultimately seems to derive from the Sanskrit word kurivinda through either the Tamil kurundam or Hindi kurand. Modern gemologists define sapphire as a gem variety of corundum, independent of color, except for those which are colored red by chromium.

This is a partial crystal of color change sapphire. While well known in synthetic examples, natural samples of color changing sapphire are quite rare. This specimen is a crude crystal, perhaps half of a typical bipyramidal corundum crystal. The crystal is transparent but a bit cloudy. The color changes from a reddish purple color to a greenish blue color. 14.82 cts.
