Iron Pyrite, otherwise known as "Fool's Gold", is a naturally occurring, perfectly formed cubic cluster of a yellow gold mineral.  The metallic and slightly brassy lustre means that countless prospectors have mistaken it for its' more valuable look-a-like.  'White iron pyrite' or marcasite is often used in jewellery, and was at the height of popularity in the Victorian era and with art noveau designers. However, we at Two Skies love to be different and have used unpolished cubic pyrite for a range of most unusual rings and pendants.
