Physical properties

Formation & geological history

Formed through the fossilization of resin from ancient coniferous or deciduous trees over millions of years (typically 30-90 million years old). It undergoes polymerization and oxidation after being buried in sediment.

Uses & applications

Primary use is in jewelry, beads, and decorative carvings. It is also of great scientific value for the inclusions of insects or plants it may contain.

Geological facts

Amber is not a stone but organic matter. It can generate static electricity when rubbed (the word 'electron' is derived from the Greek name for amber, 'elektron'). The oldest amber samples date back 320 million years.

Field identification & locations

Identified in the field by its light weight, resinous luster, and warmth to the touch. Authentic amber will float in a solution of 1 part salt to 2 parts water and smells like pine when touched with a hot needle.
