描述

You get the same crystal as seen in pictures.Here is a beautiful bismuth specimen.These are very nice and great to add to your mineral collection.I hand picked each one myself they are all very beautiful in person.These also make a great gift to give.Bismuth is element #83 on the Periodic Table of Elements. It is known as a post-transition metal. It has a relatively low melting-point of about 520 degrees F, which makes it easy to work with. Bismuth crystals form when the metal begins to cool from a molten state. The iridescent colors that bismuth crystals are known for are the result of an oxide tarnish.
