Very sharp and perfectly transparent, this sizable prism has a slightly smoked hue. We obtained a few of these in China almost 15 years ago, the exact location itself was not visited but the miners who sold these called it Cong Ly, they indicated it was not a true mine but a hillside. We have never seen any exactly like these since then. I would love to find this locality today! The bottom as seen has a break and contact where it was removed but the prism and termination are perfect undamaged by naked eye. Only with 20X magnification can I find a few micro bruises but no chips. A pretty Quartz that has both an alpine look and a Herkimer-like habit.
