What is Ruby?

Ruby is the red variety of the mineral corundum, and its color seamlessly picks up where pink sapphire stops. Only darker stones are generally called rubies, but the distinction between ruby and pink sapphire can be a matter of opinion. Ruby is sometimes more tinged with purple, and the most valued color is known as pigeon-blood red. It has been mined from the gravels of Sri Lanka since at least the 8^th century BCE, the subject of the speculation from its earliest days. Ancient Hindu and Burmese miners thought pale pink sapphires were unripe rubies.

Ruby is the solitary and glowing eye which dragons and wyverns carry in the middle of their foreheads.

Why are Rubies so rare?
