Physical properties

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

Formation & geological history

Formed from the fossilization of plant resin, primarily from ancient conifers, over millions of years spanning from the Carboniferous to the Quaternary periods.

Uses & applications

Widely used in jewelry, decorative items, and scientific research due to the occasional preservation of ancient insects and plant inclusions.

Geological facts

Amber floats in saltwater and produces a distinct pine-like scent when rubbed or heated due to the release of volatile oils.

Field identification & locations

Identified by its warm touch, low density, and electrostatic properties when rubbed with cloth; commonly found in the Baltic region, Dominican Republic, and Myanmar.
