Physical properties

Formation & geological history

Formed from the fossilization of resin from ancient coniferous trees, primarily during the Eocene epoch (about 44 million years ago). Over millions of years, the resin undergoes polymerization and loses volatile components.

Uses & applications

Primarily used in jewelry making, decorative carvings, and as a storage medium for paleontological specimens (insects trapped inside). It is also studied for scientific research into prehistoric ecosystems.

Geological facts

Unlike true minerals, amber is organic. It can trap DNA and ancient life forms in a near-perfect state of preservation. It is famous for its electrostatic properties; rubbing amber with a cloth creates static electricity.

Field identification & locations

Identify in the field by its light weight and warmth to the touch compared to stone. It can be found on Baltic Sea beaches after storms or in coal seams. A common test is the 'salt water test' where it floats in highly saline water but sinks in fresh water.
