Physical properties

Formation & geological history

Formed from the fossilized resin of ancient coniferous trees. Over millions of years (typically 30-90 million years old), the resin undergoes polymerization and burial in sedimentary layers, transforming into a stable organic polymer.

Uses & applications

Primarily used in jewelry (cabochons and beads), decorative carvings, and as a source of succinic acid. It is highly valued by collectors and scientists when it contains 'inclusions' like insects or plant matter.

Geological facts

Amber is organic, not a stone. It can contain perfectly preserved DNA and tissues of prehistoric organisms. It also exhibits electrostatic properties; the ancient Greeks called it 'elektron,' which is the root of the word 'electricity.'

Field identification & locations

Identify in the field by its light weight (it feels warmer and lighter than stone) and its ability to float in a saturated salt-water solution. Common locations include the Baltic Sea region, Dominican Republic, and Myanmar.
