8.7 x 7.8 x 6.4. These crystals, to 1.5cm, are the best I have personally seen from this famous locality for the overall size of the specimen. They have a gorgeous, silky sheen to them, the piece is 3-dimensional, and itâ€™s just plain big. Most good pieces from here are small. I suppose that is why Charlie kept it so long as one of his mixed worldwide minerals, in with his Kalahari and Indian collections which were much larger. A fine, US classic. Ex. Charlie Key.
