Beautiful Hoppered Lab Grown Bismuth From Germany - This is a large, brilliantly colored plate of lab grown Bismuth crystals from Germany. The crystals are extremely shiny and exhibit all colors of the rainbow. As you can see, this one has nice rhombic features. Bismuth is rarely found in nature and when it is, it is very bland compared to it's lab grown counterpart. This piece measures approximately 6" W and 4 1/4" T and weighs 12.5 oz. Sometimes Bismuth is made into unique jewelry. This large piece would make a lot of jewelry (if you could bear to cut it up!).
