Small Iridescent Bismuth CrystalBismuth is a byproduct that is found in a crystal form in the metals Cobalt, Nickel, Sulfide Ores, and even Silver. Even though this metal does occur naturally, the process is considered man made. Without doing this, Bismuth would not exist. Fun fact not only is this mineral gorgeous and fun to look at, but it is also used in a different form to eliminate bacteria in stomach organs, and also used to treat indigestion. What a multi functional mineral!
