Mother Nature doesn't make Bismuth Crystals!  Bismuth is rarely found in nature in its elemental form. Of growing
interest in rock shops, however, are laboratory-grown bismuth crystals. These crystals, while not natural, are nonetheless
very interesting and sought after by the mineral hobbyist, collectors and rock hounds. The unique look that these crystals
offer is really something very special! Bismuth Pellets can also be a valuable addition to your collection of metals.

Bismuth was discovered in 1753 by Claude Francois Geoffroy. It is a very unusual and rare heavy metal that is solid at
room temperature. It is more rare than platinum, ranking number 69 out of the 75 listed rare elements found on Earth’s
crust. One very interesting thing about bismuth is that its liquid form is denser than its solid form. So as bismuth
crystallizes, its solid form floats above the liquid. This effect is only found in 3 other cases (water, gallium, and germanium).

Bismuth is a white, crystalline, brittle metal with a pinkish tinge. It occurs in a native state. Bismuth is the most
diamagnetic (repels magnets) of all metals. Its thermal conductivity is lower than any metal, except mercury. Bismuth has
a high electrical resistance normally and has the highest
Hall Effect (increase in electrical resistance when placed in a
magnetic field) of any metal. High-purity bismuth can form into distinctive and beautiful hopper crystals.

Bismuth crystals are man-made or laboratory “grown”. They are normally made from commercial 99.99% pure bismuth
pellets. Bismuth melts at 271.3 degrees Centigrade / 520.34 degrees Fahrenheit / 544.45 degrees Kelvin. Bismuth crystal
growth time is between 4 to 10 minutes as they form in a cooling bismuth melt. In its solid form, bismuth is incredibly
fragile. However, the crystals form to show perfect cleavage, making it tempting to handle and touch. The reason the
crystal structure is so fragile is because the rapid growth causes hollow stepped forms, called “hopper crystals”.

The iridescent coloring ranging through reds, blues, purples, gold and greens is due to a thin layer of bismuth oxide that
forms on the surface of the crystal as it cools. This is actually interference coloring, similar to the coloring you see on soap
bubbles and on oil slicks, and is based on how thick the oxide grows. The brightness and color intensity can vary from
sample to sample, depending on the quality and purity of the bismuth used. Some labs report that adding voltage from a
small battery helps control the coloring during its formation.
