| 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. | | | | | 3.21 cts.
