корунд

Тезаурус:

1. Corundum (sapphire and ruby)
2. As a mineral, corundum has proved its value to man partly as an abrasive, which allowed it to play a key role in the shaping of jade, and partly because it has contributed two of the most keenly sought after transparent coloured gems, sapphire and ruby.
3. Corundum (Mohs 9), a crystallized mineral of the ruby group, was taken into use during the Song dynasty.
4. The most important Old World sources of corundum are located in Thailand, Burma, Sri Lanka, Kashmir and Afghanistan, which shared the characteristic that they could most readily be tapped by the India trade to the west.
