Raw Black Tourmaline In Matrix




Iron-rich black tourmaline forms black prismatic strands in a rough quartz matrix as shown in these stones. Tourmaline is the name of a large group of boron silicate minerals. These minerals share a common crystal structure and similar physical properties - but vary tremendously in chemical composition. The wide range of compositions and color zoning within crystals causes tourmaline to occur in more colors and color combinations than any other mineral group.

Why we love these:  These appearance of these stones is beautiful because of the contrast of the colors of black and white!
