Physical properties

Formation & geological history

Formed from the fossilization of tree resin secreted by ancient coniferous trees. This process, known as polymerization, takes millions of years (typically 30-90 million years old) under high pressure and temperature beneath sedimentary layers.

Uses & applications

Predominantly used in jewelry (beads, cabochons), ornate carvings, and as a source of succinic acid. It is highly valued by collectors and scientists when it contains 'inclusions' like insects or plant matter.

Geological facts

Amber is not a true stone but fossilized sap. The most famous amber lost in history was the 'Amber Room' of the Catherine Palace in Russia. It is one of the few organic substances classified as a gemstone.

Field identification & locations

Identify in the field by its light weight compared to its size and its warm feel to the touch. It can be found along coastlines (like the Baltic Sea) after storms. Collectors look for clarity and internal organic inclusions. It will produce a piney smell when touched with a hot needle.
