RUBY   Ruby is known as the "Lord of the Gems" because of its rarity and beauty. Derived from the Latin word "ruber," it simply means red. Ruby, like sapphire, is a variety of corundum and only exists as a true red in color. The finest color is vivid, almost pure spectral red with a very faint undertone of blue, as seen in the highest quality Burmese rubies, which are considered the finest. Ruby is the accepted birthstone for July. It is also the accepted anniversary gemstone for the 15th and 40th years of marriage. The highest quality rubies were said to protect their owners from all kinds of misfortune. A fine ruby assured the owner he would live in harmony with his neighbors. It would protect his stature in life, his home and land. It's protective powers were intensified when set in jewelry, and worn on the left side. Many believed rubies possessed an inner flame which burns eternally. As part of the customary fashioning process, most rubies are heated to permanently improve their color and appearance. As with all gemstones, care should be taken to protect it from scratches and sharp blows. Many fine rubies emanate from Burma, having been mined there for more than 700 years. Other sources include Thailand, Kenya, Tanzania, Cambodia, Sri Lanka, India and Vietnam.   Jewelers of America Back to Gemstone List
