Superb cluster of parallel-growth Milarite crystals from this remote mining region in Namibia! The crystals are gemmy to translucent, highly lustrous, and well-terminated. It is, of course, contacted on the back. This is material from the 1970s find, and it certainly is one of the better ones you will find for crystal quality. Most are singles. This is a meaty, big cluster. It positively glows when backlit!
