A 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.
The most valuable rubies of deep red colour called "pigeon blood" originate from Mogok Valley in Myanmar. Rubies from Sri Lanka have raspberry colour, the oldest deposits of rubies are alluvial rivers in the southwest of Sri Lanka near Ratnapura. Since modern times, rubies are also mined in Madagascar, Tanzania and Afghanistan.
Natural rubies can be treated in order to improve their quality. They can be heated or enhanced with metal oxides to obtain better colour. Fractures inside rubies can be filled with lead glass to improve their transparency etc. Rubies of the highest quality and size are very expensive they are rarer and more valuable than big diamonds.
The most beautiful and most popular rubies in the world were found in Myanmar. The world value champion is a gem weighing 32.08 carats auctioned in 1989 for 4.62 million dollars. Other interesting exemplars are the North Star weighing 166 carats and the Edith Hagen weighing 100 carats, both of them are parts of a museum collection in New York. The large ruby set in the necklace of the British royal collection has a very complex history. It comes from India and was originally owned by the sultans in Delhi. Then the Iranian ruler and warlord Tamerlan got it after conquesting Delhi. Later on the gem returned to India, then along with diamonds such as Koh-i-noor and Great Mogul it become the property of Shah of Persia Nadir. His heirs gave it as a present to the Afghan ruler. After the Sikh war in 1849 the ruby became part of the reparations paid to the East India Trading Company which donated it to Queen Victoria.
Rubies are desirable magical minerals. According to ancient Indians the ruby Manikja was the king of gems, the donor of life energy and sexual fertility.
