Quartz Quartz Quartz Quartz Quartz

Large water clear Quartz crystal from this new and now famous Quartz locality in Tanzania. Like many crystals from this mine, it has water clear transparency and lots of interesting and unusual growth patterns. It is priced so low for what it is because of a shallow ding on one back termination face. If you can live with that, it's a large and impressive crystal for what would otherwise be a four figure price.
