Another lovely Sapphire crystal from the famous island of Sri Lanka, this small thumbnail specimen has an elongated hexagonal dipyramidal form, though one of the terminations is broken off. It is in otherwise excellent condition, with well-defined edges and slightly warped but flat faces whose dull vitreous luster is interrupted by many striations that follow its basal plane. The intact termination has a very pale blue color and is transparent and quite clear, but clouds up and deepens in coloration where the termaination faces meet the "prism" faces. From there the color pales slightly and starts to slowly change from blue to red, and ends at the breakage point as a definitely pale red coloration. It is generally transparent, though the one area of cloudiness and several internal fractures and inclusions spoil its clarity. I have never seen a sapphire crystal in which the coloration makes such a smooth and gradual change as it does in this one.
