Tanzania

Location: Tanzania

The world's only known source of tanzanite was discovered deep in the foothills of Mount Kilimanjaro in Tanzania, East Africa in 1967. Geologists say the chemical environment required to form this gem is so unique that the probability of mining tanzanite from another source is less than one in a million. The quality and quantity of gem deposits vary and the production of sellable rough is not consistent at all depths. If other deposits are not located (and that seems unlikely), geologists estimate the original supply of tanzanite will dry up within 30 years.
