Physical properties

Formation & geological history

Formed from the fossilization of tree resin over millions of years (commonly from conifers). The polymerization and cross-linking of resin molecules occur under pressure and heat within sedimentary layers, typically dating from the Cretaceous to the Paleogene periods.

Uses & applications

Primarily used in jewelry (beads, pendants), as a gemstone, and for artistic carvings. It is also of extreme importance to paleontologists for preserving prehistoric biological inclusions (insects, plants).

Geological facts

Amber is not a stone but a fossilized organic substance. Some of the oldest amber dates back over 300 million years. If rubbed with a cloth, it can become electrostatically charged, a property known since ancient Greece.

Field identification & locations

Identify by its weight (extremely light) and warmth to the touch compared to glass/stone. In the field, look for it in sedimentary deposits or washed up on coastlines. High-quality pieces of 'Burmite' or 'Baltic Amber' are most sought after by collectors.
