It's the birthstone for July. It's an extremely tough and durable natural gemstone. It registers 9 out of 10, just behind the diamond, on the Mohs hardness scale. It is one of the four "precious" stones; the other three being diamond, sapphire and emerald. Its name comes from the Medieval Latin word "rubinus" meaning red. It is made of corundum, an extremely hard mineral. You guessed it! We're describing one of the most popular gemstones on planet earth; the ruby! In mythology, rubies are symbolic of power and protection. There's a reason Dorothy, in the "Wizard of Oz", wore ruby slippers. The most coveted color for a ruby is known as pigeon's blood; a deep red luxurious shade. Most rubies on the market today are heat treated to improve durability and color. FYI: The most expensive ruby ever sold was the 15.99 carat Burmese Jubilee Ruby with a Christie's New York hammer price of $14.2 million ($885,000 per carat!
