Bismuth is a natural mineral but Mother Nature doesn't make Bismuth Crystals! Bismuth is rarely found in nature in its elemental form. Bismuth is laboratory-grown crystals. These crystals, while not natural, are nonetheless very interesting and sought after by the mineral hobbyist, collectors and rock hounds.
While naturally silver, bismuth turns vivid rainbow colors when oxidized with heat and allowed to cool. Under the right conditions, this metal forms fascinating geometric patterns, or “crystals,” that typically resemble a series of stacking staircases.
