Physical properties

Hardness 2.0-2.5 Mohs, yellow to honey-brown color, resinous luster, amorphous structure, specific gravity 1.05-1.10.

Formation & geological history

Formed through the fossilization and polymerization of ancient tree resins over millions of years (Cenozoic to Cretaceous).

Uses & applications

Used primarily in jewelry, decorative carvings, and as a scientific medium for preserving biological inclusions.

Geological facts

Amber floats in saturated salt water and develops a static electrical charge when rubbed vigorously with silk or wool.

Field identification & locations

Identified by its very light weight, warm touch, and electrostatic properties; commonly found along Baltic Sea coastlines and in the Dominican Republic.
