Physical properties

Formation & geological history

Formed from the fossilization of tree resin over millions of years (typically 30–90 million years old). Subjected to high pressure and heat after being buried in sediment, transforming into a stable polymer.

Uses & applications

Used in jewelry (cabochons and beads), as an ingredient in early perfumes/medicine, and highly valued in paleontology for preserving biological inclusions (insects, plants).

Geological facts

Amber is not a true mineral because it is organic in origin. It is famous for the 'trapped in time' fossils it often contains. Ancient Greeks called it 'elektron,' which is the root of the word 'electricity' because it generates static when rubbed.

Field identification & locations

Identify in the field by its light weight (it feels much lighter than a stone of the same size) and warmth to the touch. It will float in highly saturated saltwater, whereas most fake plastic or glass imitations will sink.
