Aesthetic specimen of sharp tetrahedral Helvine crystals from Huanggang Fe-Sn deposit, Inner Mongolia AR, China. The Helvine is an uncommon silicate. The crystals are waxy lustrous with rich brown color. They sit attractively at the top forming an excellent focal point. This cluster is complete all over. Small colorless Calcite crystals, fluorescent in orange and black Magnetite are seen too. In excellent condition. On acrylic base.
