Ruby is a pink to blood-red coloured gemstone, a variety of the mineral corundum (aluminium oxide). The red colour is caused mainly by the presence of the element chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires. The ruby is considered one of the four precious stones, together with the sapphire, the emerald, and the diamond.

Prices of rubies are primarily determined by colour. The brightest and most valuable "red" called pigeon blood-red, commands a huge premium over other rubies of similar quality. After colour follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone has been treated. Cut and carat (weight) also determine the price.

Rubies have a hardness of 9.0 on the Mohs scale. Among the natural gems only diamond are harder. All natural rubies have imperfections in them, including colour impurities and inclusions of rutile needles known as "silk". Gemologists use these needle inclusions found in natural rubies to distinguish them from synthetics, simulants, or substitutes. Some rubies show a 3-point or 6-point asterism or "star". These rubies are cut into cabochons to display the effect properly.

Historically, Rubies have been mined in Thailand, Cambodia, Afghanistan and in Pakistan but red rubies are rarely found in Sri Lanka, where pink sapphires are more common. After the Second World War ruby deposits were found in Tanzania, Madagascar, Vietnam, Nepal, Tajikistan, and Pakistan. A few rubies have been found in the U.S. states of Montana, North Carolina, and South Carolina. More recently, large ruby deposits have been found under the receding ice shelf of Greenland. In 2002 rubies were found in the Waseges River area of Kenya.

Together with Ruby Zoisite, the Ruby stands for protection, health and strenght.
