Wow. This Cluster of perfectly cubed Pyrite (Iron) is growing on Sphalerite (Zinc). What a powerful combination for healing and protection. From Huanzala, Peru, it weighs in at 4.20 lbs, and is 5"X4". Stunning. It has a speck of gem quality golden Sphalerite on the bottom. Iron is the ultimate Metal for protection from negative energies, while Zinc vibrates to the Planet Uranus, the Planet of liberation and change. A fabulous combination. New.
