What is Corundum?
Corundum, so-called ‘alumina’ and ‘Al2O3’, is a crystalline form of aluminium oxide. It also has two other names that are not widely known: Ruby and Sapphire. The name ‘corundum’ is derived from the word Kurundam, which is the Tamil-Dravidian word of ruby-sapphire. Due to its gem varieties, Corundum has super high hardness (9.0 on the Mohs scale, just next to diamond).
