Tanzanite running out

20 years ago the Mirerani quarries, located in Simanjiro District of Manyara Region used to spew out large amounts of tanzanite. Tanzanite production has been drastically dropping, and like every other single source gemstone the deposit is being depleted. Its called a single-generation stone.
There seems to be no end in demand as it has become a favorite of many jewelry designers.
