1 Aura Rainbow Titanium Specimen Crystal Per Order
Bismuth is super rare in its elemental form and these beauties are a perfect combination of art and science where they are lab "grown" from commercial 99.99% pure bismuth pellets. 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, greens, purples, and golds is due to a thin layer of bismuth oxide that forms on the surface of the crystal as it cools. This is actually iridescent coloring, similar to the coloring you see on soap bubbles and on oil slicks.
