Copper ring encrusted with rough pyrite mineral

A unique design aged copper ring made out of reclaimed copper and rough pyrite mineral. This interesting mineral used to be mistaken for gold during the gold-rush. In those times it was even entitled the “fools-gold”! Apart from history, this mineral is very interesting due to it’s crystalline lattice, it naturally forms these ideally cubic crystals – a real marvel from Nature. The inner diameter is of 16,5 mm (Lithuanian size 16,5).
