Physical properties

Hardness: 2.0-2.5; Color: Honey-yellow, orange, to reddish-brown; Luster: Resinous; Crystal structure: Amorphous; Cleavage: None; Specific Gravity: 1.05-1.10 (very light/buoyant).

Formation & geological history

Formed through the polymerization of resin from extinct coniferous trees, typically from the Eocene or Cretaceous periods (approx. 30-90 million years ago).

Uses & applications

Used primarily in jewelry (beads, pendants), as a source of succinic acid, and in scientific research (paleontology) when it contains inclusions like insects or plant matter.

Geological facts

Amber is not a stone but fossilized sap. It is one of the few organic gems. Famous specimens are found in the Baltic region, which contains over 90% of the world's accessible amber.

Field identification & locations

Identify in the field by its light weight (it often floats in saltwater) and its ability to build a static charge when rubbed with a cloth. It is commonly found in beach sediments or lignite coal mines.
