Aragonite is chemically identical to Calcite.  The difference is in the geological conditions it forms under. It may be colourless, white, gray, reddish, yellowish, blue, violet, brown, or green.  It is generally found as orthorhombic crystals either as single crystals or twinned.  Aragonite is mostly found within the oxidized zone of ore deposits. Facet quality crystals may be found in the Czech Republic, Mexico, Morocco, England, Japan, Germany,Italy, France, Hungary, and some locations in the U.S.
