Jasper General Information
Jasper is usually considered Chalcedony; sometimes, however, scientists put it in a group within the quartz group because of its grainy structure.
The name jasper is derived from Greek and means “spotted stone”.
The finely grained, dense jasper contains up to 20 percent foreign materials, which determine its color, streak, and appearance. Uniformly colored jasper is rare, usually, it is multicolored, striped, or flamed. Sometimes jasper can be grown together with agate or opal. There is also some fossilized material.
