Description
Scintillating, tetragonal, brown to gemmy golden-yellow Wurtzite crystals richly cover the typically matrix. Wurtzite is an uncommon zinc, iron sulfide, a polymorph of Sphalerite and is seldom found in well-developed crystals worldwide. Wurtzite is usually found as crusts or blebs, so this is outstanding material. Classic material from the famous and ancient Kirki Mine of Alexandroupoli in Macedonia, Greece.
