Ruby is a red gemstone, a variety of the mineral corundum (aluminium oxide). The color is caused mainly by chromium. Its name comes from ruber, Latin for red. Natural rubies are exceptionally rare, but synthetic rubies (sometimes called created ruby) can be manufactured fairly cheaply. Other varieties of gem-quality corundum are called sapphires. It is considered one of the four precious gems together with the sapphire, the emerald and the diamond.

Rubies are mined in Africa, Asia, Australia, and Greenland. They are most often found in Myanmar (Burma), Sri Lanka, Kenya, Madagascar, and Thailand, but they have also been found in the U.S. states of Montana, North Carolina and South Carolina. The Mogok Valley in Myanmar has produced some of the finest rubies but in recent years very few good rubies have been found there. In central Myanmar the area of Mong Hsu also produces rubies. The latest ruby deposit to be found in Myanmar is situated in Nam Ya. In 2002 rubies were found in the Waseges River area of Kenya. Rubies are being mined at Audilamena in northeastern Madagascar. Sometimes spinels are found along with rubies in the same rocks and are mistaken for rubies. However, fine red spinels may approach the average ruby in value.

Rubies have a hardness of 9.0 on the Mohs scale of mineral hardness. Among the natural gems only diamond is harder.

Ruby gemstones are valued according to size, color, clarity and cut. All natural rubies have imperfections in them, including color impurities and inclusions of rutile needles known as "silk". If there is no silk in the stone, that shows that the stone was heated at 3000°C to give the ruby a better color of red. Usually the rough stone is heated before cutting.

ruby is a red color stone and generally worn for relationship betterment. But do not wear unless a really knowledgeable person has recommended.

Cost of the stone depends on clarity and caret of the stone. Moreover, whenever you buy any precious stones then ask for certificate and bill so that people cant fool you.
