Physical properties

Hardness 2.0-2.5; warm honey-yellow to milky translucent; resinous to greasy luster; amorphous; specific gravity ~1.05-1.10.

Formed from the fossilized resin of ancient coniferous trees during the Eocene epoch (approx. 40-50 million years ago).

Commonly used in jewelry, ornamental carvings, holistic healing items, and scientific research for paleobiology inclusions.

It floats or suspends in saturated salt water and becomes electrostatically charged when rubbed vigorously with a cloth.

Frequently washes ashore on beaches across the North Sea and East Anglia (matching the 52.0°N, 1.1°E Suffolk coast region), especially after storms.
