6-Cube Pyrite Cluster on Matrix

Size: 14 x 13 x 10cm

Weight: 1124g 

This is an exceptional, large pyrite cube cluster on matrix! There are 6 high-quality pyrite cubes all intergrown and perched on the matrix. The largest cube is 4cm long. Sharp edges and corners with only one edge showing a contact area where there was probably another cube attached sometime in its life. The other edges are all perfectly razor-sharp. The faces are shiny and in excellent condition! 

These Spanish pyrites are some of the world's most amazing mineral specimens, and people often think they are man-made. But these perfect cubes are completely natural and grow like this all on their own. They're made of iron and sulphur, and the world's best pyrites come from Spain, specifically, the Victoria Mine in Navajun. When these come out of the ground they are very fragile, and as part of the normal cleaning process they detach the cubes, clean them, and then put them back together as they were originally, but now much stronger.
