Like its neighbors of Cambodia, Vietnam, Burma, and Thailand, Laos has ruby deposits too. Unfortunately the international border between Laos, Cambodia, and Burma is known as the “Golden Triangle” due large amounts of illicit trade in jade, silver, lumber, opium, and, of course, rubies in that location.
Ruby Mining in Laos is limited, with most of its corundum production being sapphires rather than rubies. Sapphire mining has been going on in the Bokeo Province of Laos (the northwestern part of the country) since the 14 century.
There have been reports of ruby mines in the southern part of the country, with many farmers digging pits in the middle of their land trying to find valuable gems.
