Physical properties

Formation & geological history

Formed from the fossilization of tree resin, primarily from conifers and deciduous trees, over millions of years (ranging from carboniferous to quaternary periods, mostly Eocene).

Uses & applications

Used in jewelry, decorative carvings, and historically in folk medicine. Scientifically invaluable for preserving prehistoric insects and plant matter (inclusions).

Geological facts

Some amber specimens contain perfectly preserved ancient insects, feathers, or air bubbles trapped millions of years ago, providing a unique window into prehistoric ecosystems.

Field identification & locations

Found worldwide, notably in the Baltic region (Baltic amber), the Dominican Republic, and Myanmar. It can be identified by its low specific gravity, warm touch, and electrostatic properties when rubbed.
