Zincite crystals of this caliber only come from the Zinc smelters of Poland. Red Zincite Crystals are unique and very scarce. Zincite crystals are synthetic, an accidental fusion of natural and man made. Some of the green and blue specimens fluoresce under a black light. I was given the opportunity to select the highest grade red zincite crystals from a large old collection. We are offering zincites from this collection on the internet.
