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. |
