Ruby is a variety of corundum which is then colored to a deep red coloring by chromium. One of the other variations of corundum is sapphire dependent on the impurities within the mineral. The name of ruby comes from the Latin word for red, rubeus.
One of the most famous locations for rubies is the Mogok Valley in Burma, known for its deep blood red colored rubies. You can also find rubies in the United States, Thailand, Vietnam, and India. Not surprising, the ruby is known to represent life and blood and is known to increase courage. In fact, warriors in Burma would implant rubies into their skin before battle for protection and courage on the battlefield.
In past centuries, some believed this birthstone for July could predict misfortune or danger, and others claimed it would cure inflammatory diseases and soothe anger. Medieval Europeans maintained that rubies bestowed health, wisdom, wealth and success in love.
