Physical properties

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

Formation & geological history

Formed through the fossilization of tree resin over millions of years, commonly originating from coniferous forests in the Cenozoic and Mesozoic eras.

Uses & applications

Used primarily in jewelry, decorative carvings, and as a preserved medium for studying ancient insects and plant inclusions.

Geological facts

Amber floats in saltwater and can generate static electricity when rubbed with cloth. Some specimens preserve complete prehistoric ecosystems.

Field identification & locations

Identified by its warm touch, low specific gravity, and characteristic pine scent when heated. Found globally in regions like the Baltic Sea and Dominican Republic.
