The Greek origin of the word jasper, iaspis, means “spotted stone.” Jasper contains microscopic “grains” of crystalline quartz and agate has microscopic “fibers” of crystalline quartz. Although the term jasper is often applied to unidentified stones, true jaspers are metamorphic rocks. Jasper derives its colorful patterns from other minerals present, and is often named according to its pattern. It has a dull luster but takes a fine polish, and its hardness and other physical properties are those of quartz. Jasper is often sealed with petroleum products. Its polish might wash away in water, so clean with a soft, dry cloth. Jasper is mined in North Africa, Sicily, France, India, Venezuela, Germany, and in the U.S.A. Width: 8 mm.
