It forms in hydrothermal veins where mineral-rich fluids deposit sulfide minerals as they cool. Its metallic silver-gray color is due to its high lead content and dense crystal structure. These specimens typically display cubic crystal formations with bright metallic luster and may include natural matrix or minor inclusions. Each item is unique in shape, color, and pattern.
