This is an amazing cluster of 3 huge Pyrite crystals set beautifully on a Marl matrix with blue Lithium Chloritoids from from Navajun, La Rioja, Spain 🇪🇸 
A beautifully balanced piece with each crystal measuring approximately 3cm square ✨🌟💫
Pyrite for positive attitude, action and manifestation ⚡️
 
Pyrite is an iron sulphide mineral and its name is derived for the Greek word for fire.
The crystal structure of pyrite is simple cubic, and this is shown to great effect in this piece 🌟
