Org. materials have a long history of cultural importance as gemstones. The best known such minerals are amber and jet. For almost 150 years, stantienite has been considered to be a rare structural variation of Baltic amber, which is a fossilized product of plant resins. Spectroscopic examn., however, demonstrates that the material is a variety of jet or coal, which is a fossilized product of the woody portions of plants. A Turkish material called Oltu stone or black amber has similar spectroscopic characteristics to jet and stantienite and also is a coal deriv. rather than a resinous product that could be called amber.
