Simbircite
Simbircite- natural stone
Simbircite is a type of onyx belonging to the group of calcites. Its name comes from the Russian city of Symbirsk (currently Uljanowsk), where its largest deposits are found. Apart from Russia, it is sometimes also mined in Argentina. Sometimes simbircite stones can be found under other names, such as Siberian calcite or Volga amber. Simbircite mineral often forms crystals in the empty cells of ammonite shells or cracks in chalky concretions formed from the remains of ammonites, belemnites, and marine reptile bones. Simbircite is formed by the deposition of calcium carbonate on the walls of ammonite shells. Natural simbircite contains admixtures of other minerals, such as onyx, calcite, hematite, mother-of-pearl, pyrite, and limestone.

Due to the discovery of the first simbircite deposits many years ago, it has been used since ancient times in talismans and amulets. Because of its attractive natural appearance, simbircite is valued as a decorative stone. Figurines, boxes, vases, and other decorative items are made from simbircite stones. Due to its rare occurrence, simbircite is a sought-after collector’s stone. However, simbircite is most commonly used as a gemstone. Simbircite stone looks very good in jewelry such as necklaces or rings. When it comes to price, the more interesting and attractive the pattern we find on the surface of the stone, the more expensive it will be.
