Bismuth: Is It Naturally Rainbow Or Not?

Bismuth is a metal with a silvery appearance and is much loved among crystal enthusiasts for its bright, rainbow tarnish. It is considered a ‘hopper crystal’ due to its geometric shape. But is bismuth a naturally rainbow-colored crystal or not?

Bismuth: Is It Naturally Rainbow Or Not?

Well, it’s complicated. While its multicolored tarnish and its shape are naturally occurring, most of the brightest bismuth crystals you can buy have been given a colorful makeover. In fact, you can even make your own multicolored, dazzling bismuth crystals at home with the right equipment!

Bismuth is a soft, pliable metal that can be easily melted and was commonly used by ancient and medieval alchemists who tried to change base metal into gold.

Overall, bismuth is a stone that symbolizes transformation and experimentation, and we can harness its energy to change ourselves and the world around us. Read on to learn more about bismuth, its history, its properties, and how you can make it. 

The Science Of Bismuth Crystals

Bismuth has a low melting point 520 °F (271 °C), As it solidifies, bismuth expands and forms crystals. Bismuth crystals that have been grown artificially form a structure resembling a spiral staircase because of the higher growth rate of the edges. 

When bismuth crystals oxidize, they become an alluring, magical rainbow color. This is because the oxide layer that forms in the crystal surfaces varies in thickness, which causes different wavelengths of light to combine. 

The History Of Bismuth

Bismuth is a pretty rare material that is still relatively new to crystal collectors. Before the 1600s, bismuth was regularly thought to be iron or tin. It’s easy to see the confusion, as they do look alike! 

There are two origins for the name Bismuth. One belief is that it’s of German origin, and a variation of the name wismuth or weiße Mass, which translates into English as ‘white mass.’

Another belief is that the name derives from the Arabic word bi ismid which translates into English as ‘similar to Antimony,’ which is another silvery gray metal. 

Bismuth was excluded from ancient lapidaries, which are texts that catalog gemstones and their properties. Although little attention was paid to bismuth by lapidary writers, medieval alchemists were very much interested in the crystal.

Alchemists were like early chemists. They were educated people who conducted experiments in the search for everlasting life and, most famously, how to turn base metals into gold. Bismuth was referred to as tectum argenti by alchemists.

This is a Latin word that translates to ‘silver being made,’ and thought of it as the missing link between a base metal and a precious metal.

How To Make Bismuth Crystals

Equipment And Materials

Bismuth (you can buy this on specialty websites, or websites like eBay or Amazon). Two metal containers such as aluminum cans, aluminum foil formed in a bowl shape, or stainless steel measuring cups. A heat source such as a kitchen stove.

Steps To Making Bismuth

Place your bismuth in a metal container. Turn on your heat source, allowing the bismuth to melt. You may see a gray skin form, but there is no need to worry as this is totally normal. While the bismuth is melting, preheat your other metal container.

When the bismuth is melted and the other metal container is warmed up, pour the liquid bismuth from the first container into the other container.

Try to only pour the bismuth under the skin and try to stop the skin from going into the second container as it contains impurities. You can also skim off the skin using a spoon before you pour. 

Attempt to slowly cool down the melted bismuth. When cooled slowly the bismuth will create bigger crystals. You can do this by leaving the metal container on the turned off heat source, or by turning down the heat slowly. The bismuth should only be left to cool once it is solid.

Around 30 seconds after cooling, the bismuth should begin solidifying. Once this happens, pour the liquid away from the forming crystals. These crystals should appear to be set, but still have a jiggle to them. 

Be patient and allow the crystals to cool completely before you remove them from the metal container. If getting the crystals out of the container is challenging, you can place it in the freezer for a short time. 

Your bismuth crystal will not look rainbow-colored straight away. Rather, it will have a more silvery look. However, it will soon oxidize and you will be left with a beautiful rainbow color (see also ‘15 Beautiful Aurora Crystals‘). 

Final Thoughts

So while the rainbow color of bismuth is naturally occurring, you will get a more striking result by making the crystal yourself! If you would like one of these beautiful crystals to help deal with stress, then you can easily make one at home.
