Tumbled orange-and-white jasper or brecciated chalcedony

Microcrystalline quartz (SiO₂), likely iron-oxide-stained jasper; exact variety cannot be confirmed from the image

AI-generated identification · may be incorrect

Hardness about 6.5–7 Mohs; opaque, rounded and polished, with a waxy to vitreous luster. Cream-white quartz-rich areas contrast with orange-brown iron-oxide staining and darker inclusions; no obvious cleavage.

AI Estimated Value

About $1–$10 as a small tumbled stone; approximately $10–$40 if unusually attractive or sold as a quality cabochon.

Physical properties

Formation & geological history

Formed when silica-rich fluids replaced or cemented fine sediment or volcanic rock, with later iron-oxide alteration producing the orange color; commonly Paleozoic to younger, depending on locality.

Uses & applications

Used as an inexpensive cabochon, tumbled stone, ornament, and lapidary material; too small and variable for construction use.

Geological facts

Jasper is an opaque variety of chalcedony or microcrystalline quartz, and its colors commonly result from hematite or goethite. This specimen may also be a polished breccia rather than a single named jasper variety.

Field identification & locations

Look for opaque silica, glassy or waxy fracture, high scratch resistance, and lack of cleavage; a steel file should not easily scratch it. Common sources include Oregon, Idaho, Utah, Brazil, Madagascar, and Australia.
