Where do
gems come from?
Gems are found worldwide, but some areas are exceptionally
rich sources: Myanmar contributes a huge amount of the
world’s ruby supply; Australia formerly dominated the precious
opal market, although Ethiopia is now producing large
quantities. The highest volume of fine emeralds comes from
Colombia, while Madagascar is richest in sapphires. Diamond
supply has been led by Botswana in recent years, although
many stones are now coming out of Russia and Canada.
