Complete single 'Chrome Tourmaline', which is vanadium and chromium rich Dravite found in east Africa. Fine undamaged crystal with deep green color. Comes with a former dealer label showing a price of $750. I've set the minimum bid at less than half of the old dealer price.

A plate-like matrix of water-clear quartz crystals showing an excellent example of a rare gwindel habit group measuring about 2.8cm tall on the right side. Nearly perfect with only minimal contact, mainly at the edges on the back side and difficult to see. A classic Swiss specimen.
