Physical properties

Formation & geological history

Formed from the fossilization of tree resin, typically originating from coniferous trees, over millions of years (often Cretaceous to Paleogene periods, ranging from 30 to over 100 million years ago).

Uses & applications

Used in jewelry, ornamental carvings, decorative objects, and historically in traditional medicine.

Geological facts

Amber often preserves ancient insects, plant matter, and air bubbles, providing scientists with invaluable snapshots of prehistoric ecosystems.

Field identification & locations

Found in coastal regions where amber-bearing strata are eroded by the sea (such as the Baltic Sea region). Identified by its warm touch, low density, and ability to produce static electricity when rubbed.
