Simbircite from the Russian Simbirsk along the Volga River is both a gemstone and a fossil. These fossilized ammonites have formed over approx 160 million years. Under the heat and pressure of the earth the chambers of the Ammonite Laberticeras have been replaced with a complex mix of iron, magnesium rich calcite, aragonite, pyrite, marl, chabazite and quartz. The veins of pyrite were originally the 'bone' of the ammonite.
