Pyrite Cube in Matrix


Pyrite cubes in marl matrix from Navajún, Spain. These are natural pyrite minerals and are famous all around the world for their incredible formation. Originally discovered in 1965, the mine has been continually worked to this day. The chemical formula for pyrite is FeS2.

The cube itself measures between 1.5 cm and 2.5 cm, and the whole cube in matrix is approximately 5 - 6 oz.

The photo is representative of the material and does not necessarily mean you will receive one of the exact cubes pictured.

It is important to note, when cleaning your cubic pyrite NEVER clean it with water. The matrix is water-soluble and will disintegrate. Instead, dust it with something soft like a microfiber cloth or Q-Tip.
