Quartz is one of the most abundant minerals on Earth. Including agate, chalcedony, onyx, jasper and many other major varieties, quartz has a crystalline structure. Smoky quartz is a brown to black variety caused by the irradiation of aluminum-containing rock crystal. We carry smoky quartz beads in a range of round sizes, faceted shapes, donuts and chips. All of FusionBeads.com's gemstone beads are graded AB. Learn all about gemstones in our Gemstone Q and A.
