RETURN TO DISCOUNT BLUE SAPPHIRE

Chemical properties:  corundum is composed of pure alumina; its colouring is due to metallic

oxide traces or inclusions. The color of sapphire, due to iron and titanium oxide, gives its best
effect under daylight.  Electric light makes it often dark.
Gems are generally found in alluvium, but come either from basaltic slags, or from metamorphized marble.
