Amber is fossilized tree resin, which has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects including dice as seen here. Amber is used in jewelry. It has also been used as a healing agent in folk medicine.
