Physical properties

Hardness of 2-2.5 on the Mohs scale, golden-brown to orange color, resinous luster, amorphous crystal structure, and specific gravity around 1.05-1.10.

Formation & geological history

Formed from the fossilization of ancient tree resin, typically dating from the Cretaceous to Tertiary periods over millions of years.

Uses & applications

Used primarily in jewelry, decorative carvings, and for preserving prehistoric inclusions like insects for scientific study.

Geological facts

Amber floats in saltwater and can produce static electricity when rubbed with cloth due to its organic resin origins.

Field identification & locations

Identify it by its warm touch, low specific gravity, and characteristic conchoidal fracture; commonly found in the Baltic region and Dominican Republic.
