Amber

Amber is fossilized tree resin. Examples of it have been appreciated for its color and natural beauty since the Neolithic times,[1] and worked as a gemstone since antiquity.[2] Amber is used in jewelry and as a healing agent in folk medicine.

There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions.[3] Amber occurring in coal seams is also called resinite, and the term ambrite is applied to that found specifically within New Zealand coal seams.[4]
