Its past intertwines with mankind and it captures our imagination, showing us the full extent of human desires.
Ruby is the strongly purplish-red to orangey-red variety of the gemstone and mineral, corundum. A true sister to sapphire, ruby is comprised of aluminum oxide (Al2O3) and differentiates itself from its family with the inclusion of chromium as a trace element. Chromium is responsible for the color and the depth of saturation within the stone as well as the intense, glowing fluorescence that ruby can emit when iron levels are low. A pleochroic gem, ruby must be oriented appropriately when cut to maximize the red seen by the eye. This preference in hue increases rough material loss and, in combination with its uncommon formation, makes fine gem quality ruby over 1 carat extremely rare.
Ruby has been linked to man for thousands of years. Its name in ancient Sanskrit is "ratnaraj", meaning "precious stone king". Ruby is mentioned frequently in the Bible, while Hindus believed its internal, fiery glow would boil water when added to a filled pot. Marco Polo claimed that Kublai Khan attempted to exchange an entire city for one single, remarkable ruby. In the middle ages, ruby was worn to fend off the plague in Europe, while ruby trade and heists have played important roles in royal gem collections. Mostly, ruby is found from southern Asia and eastern Africa. Countries such as Thailand, Vietnam, Myanmar (Burma), Sri Lanka, Kenya, Tanzania, and Madagascar play important roles in ruby supply.
Ranking a 9.0 on the Mohs scale of mineral hardness makes ruby an ideal choice for setting in jewelry and can even wear well in a wedding set. Ruby is the birthstone of those born in July, while Capricorns of the Zodiac claim this stone as their own. The global demand for the crimson gem has created a market for ruby of all qualities and it is a material that is commonly heat treated. Gems proven without heat or further applications command a premium. Fine, unheated rubies rank are one of the most rare gems on earth, often obtaining the highest per carat prices of any colored stones at auction or market.
