Physical properties

Formation & geological history

Formed through the polymerization and hardening of ancient tree resin, typically originating from coniferous trees in forests millions of years ago (ranging from Cretaceous to Cenozoic eras, approx. 10 to 130 million years ago).

Uses & applications

Used primarily in jewelry, decorative carvings, and occasionally in scientific research due to the preservation of ancient insects and plant matter trapped inside.

Geological facts

Amber is famous for preserving delicate organisms like insects, feathers, and plant parts in exquisite detail, providing a window into prehistoric ecosystems.

Field identification & locations

Can be identified by its low specific gravity, warm touch, resinous smell when rubbed or heated, and static electricity generated when rubbed with cloth. Found globally, most notably in the Baltic region and the Dominican Republic.
