Super 7 is a combination of 7 different minerals. Amethyst, cacoxenite, goethite, lepidocrocite, rutile, smoky quartz and quartz. Our points are between 3"-4" in length. It's from a specific mine in the Espírito Santo region of Brazil and that mine is currently flooded and impossible for more examples of this unique stone to be mined out.
Each one we have is unique and may not look exactly like the crystal pictured.
