Physical properties

Mohs hardness 2-2.5, warm brown to golden color, resinous luster, amorphous crystal structure, specific gravity 1.05-1.10.

Formation & geological history

Formed through the fossilization of ancient tree resin, typically originating from coniferous trees during the Eocene epoch or older.

Uses & applications

Used primarily in jewelry, decorative carvings, and occasionally in scientific research due to preserved inclusions.

Geological facts

Amber can sometimes preserve prehistoric insects and plant matter intact for millions of years.

Field identification & locations
