Due to its grainy inclusions, it is grouped by itself, although it is considered a chalcedony (which is a rock texture made up of minute crystals.) Jasper is a dense microcrystalline quartz, i.e. composed of very fine intergrowths of quartz and moganite. On the Mohs Scale, denoting gemstone hardness where talc is a 1 and diamonds are a 10, jasper ranks at a 7. It is typically opaque with a dull to pearly luster. Because jasper polishes well, it is a frequent medium of cabochons, mosaics, and ornamental objects. Color is attributed to finely disseminated organic, hematite or geothite particles.

Jasper is found world-wide, though substantial mines can be found in Germany, Russia, France, India, Egypt and the United States.

Mystical Aspects:

It is also generally referenced as being protective in its ability to keep evil spirits away and protect against snake and spider bites.
