Physical properties

Opaque cream, tan, and reddish-orange coloration with mottled patterns; waxy to dull luster and no visible cleavage. Mohs hardness is about 6.5–7, with cryptocrystalline quartz structure; the displayed piece is polished and carved.

Formation & geological history

Jasper forms when silica-rich groundwater replaces or cements volcanic ash, sediments, or breccia, commonly with iron-oxide staining producing red and orange patterns. Its age depends on the host deposit; jasper occurs in many Paleozoic to Cenozoic formations.

Uses & applications

Used for carvings, cabochons, beads, ornaments, and inexpensive decorative objects; this small figurine has primarily collectible and ornamental value.

Geological facts

Jasper is a variety of chalcedony or microcrystalline quartz, though the term is also used broadly for opaque silica-rich rocks. The patterning is natural, while the bear shape is human-made.

Field identification & locations

Identify it by its opaque silica-rich body, hardness, lack of cleavage, and red iron-oxide markings; it should resist scratching by a steel blade. Common sources include India, Madagascar, Brazil, Mexico, and the United States.
