Amber is fossilized hardened resin of trees. It comes mainly from extinct coniferous tree liquid, which loses its volatile components over time and becomes harder. This process can take thousands of years to millions of years. Amber is a homogenous structure mostly in the form of drops or lumps and is yellow and brown in color. Inclusions of insects or plant parts are common.
