Polished amber-colored translucent stone, likely citrine or yellow chalcedony

Most consistent with quartz (SiO₂), potentially citrine; translucent yellow chalcedony is another possibility

AI-generated identification · may be incorrect

Honey-yellow, translucent, vitreous to waxy luster, apparently rounded and polished. Quartz has Mohs hardness 7, hexagonal crystal structure, no cleavage, and specific gravity about 2.65; chalcedony is similarly hard but microcrystalline.

AI Estimated Value

About $5–$30 for a small common polished piece; $30–$150+ if it is confirmed natural, high-clarity citrine.

Physical properties

Formation & geological history

Citrine forms when iron-bearing quartz crystallizes in igneous or hydrothermal environments; chalcedony forms from silica-rich groundwater in cavities and fractures. Exact age and identity require testing.

Uses & applications

Used as a gemstone, ornament, and lapidary material; quartz varieties are also important industrial silica sources.

Geological facts

The strong backlighting shows internal clouding and fractures, but the image does not reveal diagnostic crystal faces. It does not strongly resemble natural amber, which is organic resin and much softer (Mohs 2–2.5).

Field identification & locations

Test hardness against glass, inspect with a loupe for quartz crystal structure, and measure specific gravity; amber floats in saturated salt water and may smell resinous when warmed. Yellow chalcedony commonly occurs in volcanic cavities worldwide; citrine is especially associated with Brazil, Madagascar, and Uruguay.
