Ruby is one of the highest valued coloured gemstones, in fact, large rubies can fetch higher prices than equivalently sized diamonds. Ruby has been prized for centuries because of its excellent Mohs scale hardness of 9, along with its treasured rich red hue and vitreous lustre. Ruby is a variety of corundum that gets its red colour from chromium. Corundum that occurs in other colours is classified as sapphire. In its pure form, corundum is colourless. The word "corundum" comes from the Tamil "kurundam", meaning "ruby sapphire".
In the ancient Indian language of Sanskrit, ruby is called "ratnaraj", which translates as "king of precious stones". Ancient Sanskrit texts, the Bible and other historical writings refer to ruby as a precious gem, indicating the rich history and abiding appreciation of ruby gemstones. Ancient Hindus believed that by making an offering of a ruby to Krishna, rebirth as an emperor was assured. Burmese warriors believed that rubies would make them invincible, and even inserted rubies under their skin for this purpose.
Ruby is exposed to heat treatment in order to enhance the colour. This is considered to be a stable and permanent enhancement. Intact rutile inclusions (also known as "silk") provide proof that a ruby gemstone has not been heat treated. Ruby is also irradiated and treated with diffusion to enhance the colour. Other enhancements include fracture filling with lead glass, which is conducted to render heavily included gemstones fit for jewellery use. Occasionally, ruby is oiled or dyed. Despite all of the treatments that ruby can be subjected to, natural ruby gemstones are available and all reputable gemstone sellers declare any treatments or enhancements.
The most important sources for ruby include Myanmar (Burma), Thailand, Sri Lanka and Tanzania. Other sources are Afghanistan, Australia, Brazil, India, Cambodia, Kenya, Madagascar, Malawi, Mozambique, Nepal, Pakistan, Zimbabwe, Tajikistan, the USA and Vietnam.
