Feature: ☀️ Comes with gift bagBismuth 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 interference coloring, similar to the coloring you see on soap bubbles and on oil slicks.According to Judy Hall, author of the "Crystal Bible" series, Bismuth facilitates changing complex thought patterns that have become obsoletes so that a more constructive pattern is imprinted. It assists with cells that need to be raised in frequency to accommodate new energies. As suggested by its interlinked shapes, Bismuth is excellent for ensuring group cohesiveness and can assist people who are isolated or individuals who needs to integrate back into their communites.
