These are the semi-precious Tourmalinated Quartz smooth, faceted, and carved beads we currently have in stock. Tourmalinated Quartz is transparent quartz that contains needles of black tourmaline, with a luster that can range anywhere from vitreous to dull. It's valued because of the tourmaline inclusions. Tourmalinated quartz is one of the more rare members of the Included Quartz group. It is similar to rutilated quartz and is largely found in Brazil and California.
