Bismuth | Small Rough | Germany

Our stunning Small Bismuth specimens feature unique stair-step formations and vibrant, iridescent colors created by a natural oxidation process. Each piece showcases intricate geometric patterns, making it a perfect addition to any collection or display. Due to their brittle nature, handle with care. Each crystal is one-of-a-kind!  Bismuth | Small Rough | Germany  Localities: Worldwide Rarity: Common Hardness: 2 - 2.5  Measures Approx.: 20mm x 15mm x 10mm and 0.15oz Bismuth is a brittle, metallic element (Bi, atomic number 83) known for its low toxicity and striking iridescent oxide layer that displays a spectrum of colors. With a Mohs hardness of 2-2.5, it is soft and has a high density similar to lead but is significantly less toxic. Bismuth crystallizes in a distinct stair-step hopper formation due to its unique growth pattern when cooled from a molten state. It is primarily sourced as a byproduct of lead, copper, tin, and silver mining, with major producers including China, Mexico,
