Physical properties

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

Formation & geological history

Formed from the fossilization of tree resin, primarily from conifers, over millions of years spanning the Cretaceous to Quaternary periods.

Uses & applications

Used primarily in jewelry, decorative items, and historically in folk medicine. Highly valued by paleontologists for preserving ancient insects and flora.

Geological facts

Amber can sometimes trap prehistoric organisms like insects, feathers, and air bubbles, providing a direct window into ancient ecosystems.

Field identification & locations

Identified by its warm touch, low density allowing it to float in saltwater, and electrostatic charge when rubbed. Found worldwide, notably in the Baltic region and Dominican Republic.
