Geography
While rubies are mined worldwide, the best known mines are located in Thailand, Sri Lanka, Tanzania and of course, Burma (Myanmar).
Description
Rubies are members of the corundum family and are identical to the sapphire except in color.
Identification
Burmese ruby, also known as "pigeon's blood ruby," is identified by its dark, blood-red color that has a slight hint of blue. While these stones are mainly found in Burma, it is the color, not the location they are mined in, that gives them their name.
Significance
Burmese rubies are famous for their exceptional coloring. However, they are rarely found in stones larger than 3 carats. Most rubies have some inclusions (flaws), though this seldom affects their value.
Considerations
Because of the political instability in Burma, ruby production is down. In 2003, President George W. Bush signed a law banning certain Burmese products from importation. While rubies are not specified in this law, all goods that are mined are.
