Amber is found all over the world, but large quantities are found in Eastern Europe and Mexico. Amber is fossilized tree resin, so anywhere large concentrations of fossilized trees are found, amber is also likely to be found.
Amber is initially secreted as a sticky tree sap, and the preserved remains of insects or plants are often encased in amber. The semiprecious substance has been valued through the ages and used in jewelry and other artworks. It is prized for its transparency and deep yellow-orange color. There are five different grades of amber based on the size and clarity as well as the number of inclusions in the sample.
