Amber is a fossilized resin from pines and other conifers that are several thousands to millions years old. It is also called electron and is found mainly in the Baltic region. Although it is not a stone, but a hardened resin, it is used as a gemstone for the manufacture of jewelry and other decorative objects.
Inclusions, cracks and breakage surfaces are a natural phenomenon and should never be associated with wear and tear. Avoid cleaning with any alcohol-based products.
