Jasper is a member of the chalcedony family. It is usually an opaque stone with a solid color or an irregular display of colors caused by various mineral impurities. Its colors are usually red, yellow, brown, or green in color and rarely blue. The common red color is due to iron inclusions. It often contains an abundance of impurities, and therefore some regard it as a rock instead of a mineral. Patterns arise during the consolidation process forming flow and depositional patterns in the original silica rich sediment or ash. The Jasper name means "spotted or speckled stone".
Jasper is known to have been a favorite gem in the ancient world; its name can be traced back in Arabic, Persian, Hebrew, Assyrian, Greek and Latin. Jasper in mentioned many times in the Bible. Green jasper was used to make bow drills between 4th and 5th millennium BC.
