Amber

Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times.^[1] Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects.^[2] Amber is used in jewelry and has been used 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]
