Ruby

Celebrated in ancient writings as the most precious of all gemstones, rubies have been the prized possession of emperors and kings throughout the ages. It is no wonder that in ancient Sanskrit, ruby is called ratnaraj, or ‘king of precious stones’. Ruby's inner fire has been the inspiration for innumerable legends and myths, and to this day, no red gemstone can compare to its fiery, rich hues. It was believed wearing a fine red ruby bestowed good fortune on its owner - although the owner must have already had good fortune enough to possess such a rare and beautiful gemstone!

Ruby is the red variety of the corundum mineral species, while all other colors of corundum are called sapphire. It is also the most valuable, all other things being equal.This most sought-after gemstone is available in a range of red hues, from purplish red to orangish red. Ruby is readily available in sizes up to two carats, but larger sizes can be obtained. However, in its finest quality, any size ruby can be scarce. Ruby makes an excellent accent gemstone because of its intense, pure red color. Ruby is found throughout Southeast Asia & Africa, with Mozambique, Madagascar and Myanmar (Burma) producing the most exquisite examples of this gemstone.

Fine ruby is still exceptionally rare. After being extracted from the earth, rubies today are commonly heated to high temperatures to maximize the purity and intensity of their red hue. Impurities may also dissolve or become less noticeable after heating. However, heating will only improve the color if the gemstone already contains the chemistry required. Over 95% of the world’s rubies are subjected to heat treatment to improve their color. The rare ruby that comes out of the ground with no further enhancements necessary is a true treasure of nature and amongst the most valuable gemstones on the planet.

Ruby is the birthstone for July and the gem for the 15th and 40th anniversaries.
