Physical properties

Hardness: 2.0-2.5 (Mohs), Color: Yellow to deep orange, Luster: Resinous, Crystal structure: Amorphous, Cleavage: None (conchoidal fracture), Specific Gravity: 1.05-1.09 (floats in salt water)

Formation & geological history

Formed from the fossilized resin of ancient coniferous trees, primarily dating from the Eocene epoch (approx. 30-50 million years ago) in marine or deltaic deposits.

Uses & applications

Used primarily in jewelry (beads, pendants), as a gemstone, in perfumes, and as a medium for scientific study of prehistoric life (inclusions).

Geological facts

Amber is organic, not a mineral; it often contains 'inclusions' like insects or plant matter that are millions of years old. When rubbed with a cloth, it can become electrostatically charged and attract small pieces of paper.

Field identification & locations

Identify in the field by its light weight (warmer to the touch than stone), ability to float in saturated salt water, and its reaction to heat (smells like pine). Commonly found in Baltic Sea regions as beach-washed pebbles.
