Ruby and sapphire both belong to corundum. Therefore, they consist of similar main constituents. The trace element in ruby, chromium, is the reason why ruby is red in color. Other elements, like titanium or iron, give the gem purplish red or orange color tone. Generally, in jewelry industry, “pigeon blood” is used to describe the most valuable ruby.
Ruby was mentioned in Bible long time ago. Ruby symbolizes Jewish tribe. In Asia, people started using rubies from Eastern Han Dynasty. In Ming and Qing Dynasty, emperors and officers used rubies to decorate and identify the social status.
Myanmar is an important place of origin for ruby. There was a myth saying that if the ancient warriors embedded the ruby into their flesh, they could be bulletproof! Shwedagon Pagoda, a must-go attraction of Myanmar, has also used abundant rubies to decorate its world-known Golden Stupa. Up till 2015, the biggest ruby of the world is “Carmen Lúcia Ruby”, which is over 23-carat and originated in Myanmar.
As mentioned in “Colored gem kaleidoscope - Emerald”, it is acceptable that there are minor impurities or cracks in emerald due to its nature. For the optimization of ruby, “thermal treatment” can increase its transparency and brightness. After treatment, the color of ruby will stabilize. The technical term of this thermal treatment procedure is “heat treatment”. It is a generally accepted method. Most importantly, it does not damage the gem value.
Sometimes, a natural gem without any treatment may have so many impurities and defects that its value may be lower than gems under suitable treatment. Of course, fake gems are not included! Anyway, it is uncommon to find a 5-carat or above ruby due to its property. Do pay more attention if you come across a big and flawless Ruby.
