Physical properties

Formation & geological history

Ancient plant resin hardened and polymerized over millions of years, often preserved in sedimentary deposits; geological age depends on the deposit, commonly tens of millions of years.

Uses & applications

Used for beads, pendants, ornaments, and collecting; historically also used for small carvings and decorative objects.

Geological facts

Amber is fossil resin rather than a mineral, and may preserve insects or plant fragments.

Field identification & locations

Lightweight feel, warm touch, and static charge after rubbing can support identification, but tests should avoid damaging it. Major sources include the Baltic region, the Dominican Republic, and Myanmar.
