| Additional Information |
| Another native cut rock crystal (clear quartz) with imbedded black tourmaline (schorl: mineral name) crystals. In this case the tourmaline crystallized first and was entrapped by later growing quartz crystals. Green and pink tourmalines have also been found embedded in quartz crystals and command far higher prices.
