Pyrite on Matrix from Spain

Size: 11.8 x 10.6 x 9.9cm 

Weight: 1.2kg 

Here is a very nice, perfect cube of shiny pyrite on matrix from Spain. The cube measures 3.7 x 3.7 x 3.8cm. They say nature doesn't create straight lines, but that's not true when it comes to Spanish pyrite because these are natural pyrite crystals that grow in perfect rectangular shapes with straight edges and sharp corners. 

This specimen comes with a custom display base.
