The bible aptly describes the value of a Ruby in the saying "more precious than rubies". The ancient language of Sanskrit describes the Ruby as a "RatnaRaj" which translates as the King of precious stones. The word ruby comes from the Latin word "ruber". Today the ruby is valued far more than even the best in colorless diamonds. Ruby is a crystalline form of aluminum and it is one of the most durable of all minerals in existence. Of the mineral corundum, the ruby is the gem quality. Corundums are very hard and in its most common form it is used as an abrasive. The value of a ruby is determined by its color. We all know that red is an indicator for top quality gems. These will not have any brown or blue overtones. The ruby is a very intensely colored substance and at its best, the red looks like glowing coal. In ancient times, these perpetual fires that never extinguished themselves were thought to have magical powers. The value of a ruby is decided by three other factors viz. cut, size and clarity. Perfectly translucent rubies with no flaws visible to the naked eye are the most valuable. The cut of the ruby decides how lively and attractive the ruby looks. If light were reflected across the surface of the ruby evenly then that would indicate that it is a well cut stone. Large rubies are rare; hence the bigger your ruby, the more expensive it will be. Some rubies have a six point three ray star. These are star rubies and to display the effect they are cut in a smooth domed cabochon
