Rubies are a form of corundum, which is the second hardest mineral after diamond. The most valued are clear, deep red - termed "pigeon's blood". Some rubies display a star when illuminated because of an effect called asterism. Asterism is caused by inclusions, which are needle-like extensions of other mineral crystals (such as rutile) trapped within the primary stone. Many stones that are not rubies are nevertheless called rubies. The balas, or balas ruby, for example, is a type of spinel; the Bohemian ruby is rose quartz; the Siberian ruby is red or pink tourmaline; others are varieties of garnet.
Synthetic rubies are used as gems, but most of the production is used in the manufacture of watches and instruments. Ruby is the Birthstone for July. This crystal is from Brazil.
