Polished red gemstone pendant, likely red jasper or brecciated jasper

Jasper: microcrystalline quartz (SiO₂), commonly with hematite or iron-oxide inclusions

AI-generated identification · may be incorrect

Opaque deep red to burgundy, vitreous-to-waxy polish, fine-grained and massive; Mohs hardness about 6.5–7, no visible cleavage, specific gravity roughly 2.5–2.9. The stone is wire-wrapped in metal and cannot be classified confidently from appearance alone.

AI Estimated Value

Approximately $15–$60 for a typical handmade pendant; $75–$200 if the stone is unusually fine or actually a rarer gem material.

Physical properties

Formation & geological history

Jasper forms when silica-rich fluids replace or cement volcanic, sedimentary, or altered rock, with iron oxides producing the red color; ages vary widely, commonly Paleozoic to Cenozoic. If the material is ruby or garnet instead, its origin and classification would differ substantially.

Uses & applications

Used for cabochons, pendants, beads, carvings, and decorative objects; the wire-wrapped setting is handcrafted jewelry. Common jasper has modest commercial value.

Geological facts

The uniformly opaque red appearance favors jasper or iron-rich quartz over transparent ruby. A polished surface can hide brecciation, banding, or mineral grains.

Field identification & locations

Field identification: opaque red stone with black, gray, or cream mottling, conchoidal fracture, and no cleavage suggests jasper; streak, refractive index, or hardness testing can distinguish it from garnet and ruby. Common sources include India, Madagascar, Brazil, Australia, and the western United States.
