Red-and-blue jasper (likely ocean jasper or dyed/polished jasper)

Microcrystalline quartz, chiefly SiO₂; jasper is an opaque chalcedony variety colored by iron oxides and other impurities

AI-generated identification · may be incorrect

Hardness about 6.5–7 Mohs; opaque burgundy-red and blue-gray, with a dull to waxy luster and cryptocrystalline structure. The rounded, smoothed shape suggests a tumbled or naturally water-worn specimen; exact identification is limited by the image.

Physical properties

Formation & geological history

Jasper forms when silica-rich fluids replace or cement volcanic or sedimentary material, commonly with iron-oxide staining; formation ages vary widely, from Precambrian to younger volcanic settings. Blue coloration may reflect other minerals or artificial dye/coating.

Uses & applications

Used for cabochons, beads, carvings, tumbling, ornaments, and lapidary work; durable but not typically a high-value gemstone.

Geological facts

Jasper is a variety of chalcedony rather than a single mineral species. Red coloration commonly comes from hematite or other iron oxides.

Field identification & locations

Look for opaque material, fine grain, waxy luster, conchoidal fracture, and no visible cleavage; it should resist scratching by a steel knife. Common sources include India, Madagascar, Brazil, the United States, and Indonesia.
