DRAVITE TOURMALINE - These are awsome black (dravite) sparkling beauties freash out of PERU. The supply of these are limited as all that were available were two small flats and I picked out the best 3 of the lot. Many were smaller spheres that I passed. This one is 2" across (50 mm ) and the only one with great crystal pockets including fine white mica groupings. Comes with plastic stand pictured in middle. Weight 0.46 lbs.
