Pyrite geometric cluster

Pyrite is one of the most astonishing species in the mineral kingdom due to its ability to form perfectly geometric cubes. Formerly nicknamed "fool's gold" because of its resemblance to gold, it can also naturally contain small amounts of gold or silver. The ancients already knew pyrite for the sparks it produces when struck. Pyrite is cubic because its iron and sulfur atoms naturally organize themselves into a cubic crystal system, giving rise to these regular and characteristic forms. This special piece brings together a superb cluster of pyrite crystals, composed of several cubes with golden metallic reflections, offering a formation that is both graphic and spectacular.
