Ruby is the birthstone of July.

RUBY: Ruby is a red stone in the Corundum group of stones. Corundums are a 9 on the Mohs Scale of hardness, second only to the Diamond. One of the most famous gemstones on earth, it like other Corundums, is simple aluminum oxide. Inclusions of chromium are what give Ruby its famous red color. The word ruby comes from the Latin word “ruber” which simply means, “red colored”.
