Physical properties

Formation & geological history

Formed as ancient tree resin that hardened and polymerized over millions of years, commonly in sedimentary deposits; Baltic amber is largely Eocene in age, around 34–56 million years old.

Uses & applications

Used in jewelry, ornaments, and collections; historically used for small carvings and decorative objects.

Geological facts

Amber may preserve insects, plant fragments, and other organisms. It can produce a characteristic resinous scent when gently warmed, but should not be tested with an open flame.

Field identification & locations

Common sources include the Baltic region, the Dominican Republic, and Myanmar. It is lightweight, warm to the touch, and often contains bubbles or inclusions; imitation resin and glass are common.
