Ruby: July's Birthstone

As the July birthstone, ruby has been highly regarded throughout history as one of the most beautiful and vibrant, yet resilient gems. The red flourescence that the ruby emits is not only important in the world of jewelry, but is also used as the powerhouse of red light in lazer pointers. Ruby is the red variety of Corundum, making it a seriously valueable gemstone if found without flaws or in a transluscent state.
