Corundum gemstones include rubies and sapphires.

They are the two recognized in the world. High-end gems-that is to say: ruby is red corundum, while sapphire is the general term for corundum of various colors other than red.
The value of high-end rubies is comparable to that of high-quality diamonds. People have known and used red and sapphire for thousands of years, and they have been described in the Bible and ancient Indian Sanskrit (a very old ancient Indian language). Ancient people also believed that red and sapphire could be used as medicine. Selon la légende, ruby powder could treat digestive tract diseases, and sapphire could be used to treat eye diseases.
