Jasper is an opaque chalcedony that comes in a wide variety of colors. Fancy Jasper is the name given to the group of jasper known for its scrumptious color palette of mauves, lilacs, creams and greens all mixed together. The term "Jasper" itself comes from the Greek word iaspi, meaning "spotted stone." Jasper is a gemstone that has been used all over the world. The ancient priests of Egypt carved jasper into beautiful jewelry while the Minoans used jasper for seals.
While jasper is widely available today, the gemstone was once treasured as a valuable stone. Jasper gemstones are found all over the world, but Fancy Jasper has large deposits in Africa and Brazil. Jasper in general is an impure silicon dioxide with unique patterns formed during mineral consolidation that creates the various types of this stone.
