Burmese rubies historically comes from the Mogok stone tract.
The history of mining in Burma is long, complex and turbulent and
date back thousands of years. Gems occur in a gravel layer called
Byon at a dept of 20 to 100 feet, and are recovered by rudimental
washing and screening and then hand-picking of encouraging-looking
pebbles. Today, the Mong Hsu tract is also producing gem quality
stones. Very fine Burmese stones over 5 carats are today extremely
rare and can command ten times as much the price of a 5 carats
diamond. Other producers of fine rubies are Thailand,
Pakistan, Vietnam, Ceylon, East Africa. |
