This is a 2.9 oz, 2.5” by 1.9” by 1.8” cluster of well-terminated black tourmaline from Madagascar. The cluster is a number of clack tourmalines that gather together like a set ups for a fire. There are four main crystals and a few smaller ones and there is a golden healer stained calcite in the lines along the sides. It’s a very unusual formation and it sits securely on the flat base … it will be a nice addition to your collection!
