Likely tumbled amber or orange chalcedony

Uncertain from image; possibly amber (fossilized resin, chiefly C10H16O) or carnelian (microcrystalline quartz, SiO₂)

AI-generated identification · may be incorrect

Small orange-brown, translucent, rounded fragment with a waxy to resinous luster. Amber has Mohs hardness 2–2.5 and very low density; carnelian has hardness 6.5–7, glassy/waxy luster, and quartz’s trigonal structure.

Physical properties

Formation & geological history

Amber formed from fossilized tree resin, commonly in Cretaceous–Cenozoic sediments; carnelian formed when iron-bearing silica filled cavities in volcanic rocks, generally in younger sedimentary or volcanic settings.

Uses & applications

Amber is used for jewelry and ornaments; carnelian is used for beads, cabochons, carvings, and decorative objects. The specimen is likely worth little unless unusually clear, large, or historically significant.

Geological facts

A warm needle may produce a pine-like odor in amber, but this test can damage it. Carnelian typically leaves a white streak and will scratch glass; amber will not.

Field identification & locations

Common amber sources include the Baltic region and Dominican Republic; carnelian is widespread, including India, Brazil, and Uruguay. Estimated value: $1–$20 for a small common piece; $20–$100+ if confirmed high-quality amber or gem carnelian.
