Amber

Physical Properties

Hardness: 2.0-2.5 (Mohs scale), Color: Honey-yellow to reddish-brown, Luster: Resinous, Crystal Structure: Amorphous (organic material), Gravity: 1.05-1.10.

Formation & Geological History

Formed from the fossilization of resin from extinct coniferous and deciduous trees, typically dating from the Cretaceous to early Neogene period. It is fossilized tree resin, not sap.

Uses & Applications

Used primarily in jewelry making, ornamental carvings, and historical perfumery. Also of supreme value in paleontology for preserving ancient life forms (inclusions).

Geological Facts

Amber is one of the few organic 'gemstones.' If you rub it with a cloth, it becomes statically charged and can pick up small bits of paper. It floats in saltwater but sinks in freshwater.

Field Identification & Locations

Identify by its warmth to the touch compared to cold stone, its light weight, and its ability to float in a saturated saltwater solution. Common on the shores of the Baltic Sea.
