Tourmaline

Old blue cap Tourmaline from the Charlie Key collection. Grades from a deep pure blue at the termination to a lighter blue, then an orangey red, and finally to a more raspberry red. A complete floater that is naturally etched at the bottom. Translucent to gemmy throughout. I've only seen a couple similar crystals, both also out of the Charlie Key collection. My gram scale only go to 100 grams, so I had to use my postal scale which measured it at a little over 107 grams.
