Burma rubies are the most precious form of rubies because of their distinct 'pigeon blood red color' or 'pink-red' color. Belonging to the corundum family this stone is one of the most sought after gemstone and is used to compare all other 'red' color gemstones. The result of the significant red color in Burma Ruby Stone is because of the presence of 'chromium'. Sapphires and Ruby both belong to the corundum family but a sapphire stone can be found in all colors except for the distinct red color present in a Ruby. This 'red color' is what makes Ruby such a special stone. The red color in a ruby is florescent showcasing high intensity of color.
Rubies originated in the mines of north-central Burma, Mogok Stone Tract. The origin of Burma Rubies dates back to 500 years ago and this mining center still remains the largest exporter of the Ruby stone. Ruby, jade other special gems are uniquely found in this area making Burma (Myanmar), the fifth-largest export hub of gemstones. The earliest mining activity in Burma began in 1597 after which it was taken over by the King Of Burma. Rubies have been found since that time.
