Small yellow-brown translucent mineral pebble, possibly citrine or yellow quartz

Quartz (SiO₂), tentatively; image alone cannot confirm identification

AI-generated identification · may be incorrect

Translucent yellow-brown, vitreous-looking surface; quartz has Mohs hardness 7, hexagonal crystal structure, no cleavage, and conchoidal fracture. The specimen appears rounded and opaque in places, so properties cannot be verified visually.

Physical properties

Formation & geological history

If quartz, it formed from silica-rich fluids or cooling magma; its geological age and exact formation environment cannot be determined from the image.

Uses & applications

Quartz is used in jewelry, glassmaking, electronics, and as a mineral specimen; this small piece may have modest collectible value.

Geological facts

Yellow quartz is often sold as citrine, though some commercial citrine is heat-treated amethyst.

Field identification & locations

A hardness or streak test and inspection for crystal habit would help distinguish quartz from other yellow minerals. Similar material occurs worldwide; the image does not establish a specific locality.
