Amber (possibly rough amber)

Fossilized tree resin; chemically a complex organic mixture, commonly classified as succinite when Baltic in origin

AI-generated identification · may be incorrect

Honey to orange-brown, translucent, resinous luster, with irregular fracture and no crystal structure or cleavage; Mohs hardness about 2–2.5, specific gravity roughly 1.05–1.10. The pictured piece’s identity cannot be confirmed from appearance alone.

Physical properties

Honey to orange-brown, translucent, resinous luster, with irregular fracture and no crystal structure or cleavage; Mohs hardness about 2–2.5, specific gravity roughly 1.05–1.10. The pictured piece’s identity cannot be confirmed from appearance alone.

Formation & geological history

Formed when ancient tree resin was buried and gradually polymerized over millions of years; major deposits include Baltic sediments, often about 25–50 million years old.

Uses & applications

Used for beads, pendants, carvings, and collectible specimens; also valued for preserved inclusions. It is too soft for most construction or industrial uses.

Geological facts

Amber is fossilized organic resin rather than a mineral, and some pieces preserve insects or plant matter. Imitations include copal, plastic, and glass.

Field identification & locations

Look for low density, warm feel, resinous fracture, and electrostatic charge after rubbing; avoid flame or solvent tests on valuable pieces. Common sources include Baltic shores, the Dominican Republic, and Myanmar.
