Amber-colored chalcedony (carnelian), possibly amber

Chalcedony: microcrystalline quartz (SiO₂); amber: fossilized tree resin

AI-generated identification · may be incorrect

Translucent orange-brown, waxy to vitreous luster, conchoidal fracture, no cleavage; chalcedony hardness ~6.5–7 Mohs and specific gravity ~2.6. The image most strongly suggests rough carnelian/chalcedony, though amber is a visual possibility.

Category: mineral
Identified: August 31, 2026
Method: Standard

AI Estimated Value

About $5–$30 for a small rough carnelian piece; attractive translucent specimens may reach $50–$150. Genuine amber commonly ranges from $10–$100+, depending on clarity, inclusions, and provenance.

Physical properties

Formation & geological history

Carnelian forms when silica-rich groundwater fills cavities and fractures in volcanic or sedimentary rocks, commonly in Cenozoic to older formations. Amber formed from fossilized resin, typically tens of millions of years old.

Uses & applications

Carnelian is used for beads, cabochons, carvings, and ornamental objects; amber is used in jewelry and scientific/collector specimens. Neither is generally a major construction material.

Geological facts

Carnelian is orange chalcedony colored mainly by iron impurities. Amber is much lighter (specific gravity ~1.05–1.10), warm to the touch, and may float in salt water; it can smell resinous when gently warmed.

Field identification & locations

Test cautiously: chalcedony scratches glass and feels stone-dense, whereas amber is easily scratched by steel and may show resin inclusions. Common sources include India, Brazil, Uruguay, Madagascar, and the Baltic region.
