DescriptionTourmaline is a really common crystalline mineral, but most are tiny, low quality, poor color. Colors other than, essentially, black, are uncommon.There are many spots in the world that have been renowned for millennia for their interesting mineral specimens. For a few years I had suppliers in Pakistan. They sent me interesting specimens.Over the decades I’ve been selling collectibles my market has been about 97% coins, 2% paper money, 1% everything else.
