Very fine intergrown cluster of jet-black crystals, with the largest being the full 2.5 cm and doubly-terminated! The luster ranges from very good along the prism faces to average on the terminations. Sadly, there is a contact on the back, but this is still an excellent specimen of the species and displays superbly from the front.
