Description
Here is an neat formation of a pyrite showing the classic, dramatic and rare twinning in pyrite known as “iron cross twin.” The pyrite crystal has a thin, metallic layer of goethite on the surface and well defined features! “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 just like this one does. The iron cross twin law is well known and exhibited in specimens from various localities, but rarely does one find good-sized complete crystals. This is a nice example of this rare material from the finds made 5-6 years ago.
