Bismuth is a heavy, brittle metal that is rarely found free in nature. It was first discovered in 1826. Bismuth crystals are an excellent choice for collectors, as the crystals are often very colorful and each one is unique due to the natural variations that can be found among them. You will receive one piece of bismuth crystal mineral. You may not see the same pattern as in the photo. This material is fragile and you should handle it with care. Please be aware that each piece is unique and is not a perfect sphere.
