Myanmar has long been recognized as the locality associated with most desirable rubies in the world.WithinMyanmar,the most famed region is the Mogok Valley,or Mogok Stone Tract,in the PyinOoLwin district and Mandalay Division,North East of Mandalay: some of a few dozen square miles,of which only a portion is gem-bearing.
Although it is uncertain when mining first began in Mogok,accounts indicate that rubies have been source in the Mogok area for wellover a thousand years. The earliest surviving records of mining activity began in 1597.Myanmar rubies,especially the ones from Mogok,have since sustained the strongest renown.
These Mogok-Type rubies typically possess a red body colour and red UV-fluorescence. In addition, they may contain tiny amounts of light-scattering rutile silk and a swirl-like growth pattern in internal features and properties. It is this combination of features which gives these rubies their characteristic appearance.
This may indicate that this gem was unearthed from the historic Burmese locality of the Mogok Valley. Natural Myanmar rubies of the size,colour and high clarity are extraordinary and represent a great rarity in the market today.
