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 to manufacture jewelry and other decorative objects.
As the amber drips from the tree, it is likely that several micro-organisms are trapped within. Its commercial value then increases due to the scarcity of the finding.
Inclusions, cracks, and fracture surfaces are natural features and should not be regarded as signs of damage.
