Physical properties

Formation & geological history

Formed from the fossilized tree resin of ancient coniferous and deciduous trees. Geological age ranges typically from 30 to 90 million years old (Eocene to Cretaceous). It forms in forest environments through polymerization and burial.

Uses & applications

Primary use is in jewelry, beads, and as decorative ornaments. It is also highly valued by scientists for the preservation of prehistoric inclusions like insects and plant matter.

Geological facts

Amber is organic matter, not a stone. It is one of the few organic gemstones. Famous specimens include the 'Amber Room' in Russia and pieces containing perfectly preserved prehistoric mosquitoes, which inspired the science in Jurassic Park.

Field identification & locations

To identify in the field, check for its light weight and resinous feel. It can be tested by rubbing with a cloth to see if it develops a static charge (electrosity) or by seeing if it floats in saturated saltwater. Commonly found in the Baltic Sea region and the Dominican Republic.
