  • This piece shows the amazing and rare twinnng in Pyrite known as “Iron Cross Twin”.


    “Iron Cross Twins” are twinned crystals exhibiting the forms of two pentagonal dodecahedra (also known as Pyritohedra). These Twins display edges crossing at 90 degrees, and in an idealized/model Twin, these edges form a cross. In nature, the edges that form the cross are sometimes not continuous or are not equal to one another, so a Pyrite crystal that is twinned according to “Iron-Cross law” may or may not exhibit an actual cross shape, but in any event the relationship of the crystals exhibits the “crossed symmetry”.


  • Pyrite - Iron Cross Twin, otherwise known as Goethite PS. After Pyrite, is Pseudomorph Pyrite, meaning it has been replaced with Goethite on the surface.

  • The iron cross twin law is well known and exhibited in specimens from various localities, but rarely does one find good-sized complete crystals. The most remarkable, and spectacular specimens are from Gachalá - Colombia.

  • I work directly with local inhabitants of Colombia and personally import these minerals.

  • I am a geologist, explorer, collector and seller of gems, minerals and jewels. I select the best quality pieces.
