Amber is fossil tree resin, which is appreciated for its color and beauty. Good quality amber is used for the manufacture of ornamental objects and jewelry. Although not mineralized, it is often classified as a gemstone.
BALTIC AMBER
Baltic amber has a very wide distribution, extending over a large part of northern Europe and occurring as far east as the Urals.
Baltic amber yields on dry distillation succinic acid, the proportion varying from about 3% to 8%, and being greatest in the pale opaque or bony varieties. The aromatic and irritating fumes emitted by burning amber are mainly due to this acid. Baltic amber is distinguished by its yield of succinic acid, hence the name succinite proposed by Professor James Dwight Dana, and now commonly used in scientific writings as a specific term for the Prussian amber. Succinite has a hardness between 2 and 3, which is rather greater than that of many other fossil resins. Its specific gravity varies from 1.05 to 1.10. An effective tool for Baltic amber analysis is IR spectroscopy. It enables the distinction between Baltic and non-Baltic amber varieties because of a specific carbonyl absorption and it can also detect the relative age of an amber sample.
