Amber is the fossilized resin from ancient forests. Amber is not produced from tree sap, but rather from plant resin. This aromatic resin can drip from and ooze down trees, as well as fill internal fissures, trapping debris such as seeds, leaves, feathers and insects. The resin becomes buried and fossilized through a natural polymerization of the original organic compounds. Most Amber is extracted from the sea by various methods but some are found underground in areas that used to be waterlogged. The highest concentration of quality Amber is found in the Baltic region of Europe, but it can also be found in further-flung places like Mexico, Sumatra and the Dominican Republic which is famous for blue amber The oldest amber discovered on Earth is about 320 million years old. The Baltic Amber we use at Atlas is between 44 and 100 million years old.
