About Graphic Jasper Gemstone
Jasper is a variety of quartz with a chemical composition composed primarily of silicon dioxide. Jasper is usually considered a chalcedony, but some scientists classify jasper as a separate type because of its distinctive grainy structure. Jasper comes in colors, mostly striped, spotted or flamed. Jasper is always opaque in clarity, even in thin slices. Jasper is cut and polished into cabochons and used as beads for necklaces and bracelets. It is also carved into cameos which can be worn as pendants. The name Jasper is derived from the Greek and means “spotted stone”. Jasper is common and found worldwide. Important deposits exist in India, Russia, Kazakhstan, Indonesia, Egypt, Madagascar, Australia, Brazil, Venezuela, Uruguay and the United States.
