A display specimen of a pyrite crystal cluster from Peru. Pyrite is a well known and common mineral found all over the world, it is commonly known as fools gold, a name possibly derived from the fact that many gold prospectors would mistake it for gold due to it’s metallic lustre and brassy colour. It is an iron mineral and fairly dense and is so named from the Greek word ‘pyritēs’ which means ‘in fire’ or ‘to fire’ which is a reference to the fact that it was historically noted for created sparks when struck by metal. It is often found in quartz veins or other rocks and is a common mineral and likely one that most people will come across in their childhood at some point. This sample displays numerous small crystals of pyrite within a matrix. The crystals show both cubic and pyritohedron structures, this has given the crystals striated faces. This piece weighs roughly 970 g and measures approximately 12 x 9 x 5 cm at its widest points. This sample is supplied with an information label and would make an excellent addition to any mineral collection.
