Amber is a fossilized resin from pines and other conifers that are several thousands to millions years old. 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. Due to its beneficial properties it has been treasured as one of the most popular gemstones since ancient times.
Pressed amber is the material created by compressing amber powder and fragments collected during the processing of pure amber. It is cheaper, heavier and slightly more durable.
