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 aregenerally found in alluvium, but come either from basaltic slags, or from metamorphized
marble. | |
