Physical properties

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

Formation & geological history

Formed through the polymerization and fossilization of tree resin, primarily from conifers, over millions of years spanning from the Carboniferous to the Quaternary periods.

Uses & applications

Used in jewelry, ornamentation, and occasionally in scientific research due to preserved inclusions of ancient flora and fauna.

Geological facts

Amber floats in saltwater and can produce static electricity when rubbed. Exceptional specimens frequently preserve fragile prehistoric insects.

Field identification & locations

Identified by its warm touch, low density, and pleasant pine-like scent when gently heated. Found globally, famously along the Baltic Sea coast.
