Because the ancients thought itsglowing red color was due to an inextinguishable inner fire, rubywas also always associated with courage and power.Throughout most of recorded history, ruby has been the mostvaluable of gems. It was believed wearing a fine red ruby bestowedgood fortune on its owner — although the owner must havealready had good fortune enough to possess such a rare andbeautiful gem!Despite all the best efforts of gem merchants to use technologyto enrich color, fine ruby is still exceptionally rare. After beingextracted from the earth, rubies today are commonly heated tohigh temperatures to maximize the purity and intensity of theirred hue. Impurities may also dissolve or become less noticeableafter heating. However, heating will only improve the color ifthe gem already contains the chemistry required. Occasionallyrubies with small imperfections are permeated with a silicatebyproduct of the heating process, which helps to make smallfissures less visible. This enhancement, like heating, is permanentand rubies, whether enhanced or not, remain among the mostdurable of gems.Today a new method of artificially coloring the surface of palerrubies or dark purple sapphires through the diffusion of beryllium,or a similar element, has made the red of ruby more affordable.Although this method is not yet common, in the future berylliumdiffusedrubies may offer an affordable alternative to eitheruntreated or heat-enhanced rubies, which are both much morerare. However, recutting or repolishing may affect the color ofsome beryllium-diffusion treated stones.A M E R I C A N G E M T R A D E A S S O C I A T I O N
