Physical properties

Hardness 2-2.5 on Mohs scale, yellow to brown-orange color, resinous luster, amorphous crystal structure, conchoidal fracture, specific gravity 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, ornamental carvings, and for preserving prehistoric inclusions like insects for scientific study.

Geological facts

Amber floats in saltwater and can generate static electricity when rubbed with cloth.

Field identification & locations

Identified by its warm touch, low density, and pleasant pine-like scent when rubbed or heated. Commonly found in the Baltic region and the Dominican Republic.
