Further details
Explorers to Burma during the 16th Century were in awe at the sheer number and quality of rubies that were worn by the King and his courtiers. The most desireable specimens come from the Mogok Stone Tract and prior to a road being built during the early 20th Century, it took three weeks to get to the tract from Rangoon. The word Mogok comes from the Burmese word "Mochok" meaning "nightfall camping ground".
The most common procedure for extracting the rubies is by open cast mining with the gem baring gravel normally only 5 to 15 meters deep, but due to adverse weather conditions, it was only possible to work from November to March.
With the nationalisation of the mines completed by 1970, the government controls the supply of rubies and this particular area now yields very few important stones. Therefore to be able to purchase a gem quality unheated Burmese ruby is indeed a rare event.
