Fantastic 122ct rainbow Bismuth

This eye catching piece shines in a full spectrum of rainbow colors with gorgeous angular formations. Bismuth has the unique property of being able to melt at low heat (you can actually do it on your stove), and it creates these beautiful geometric patterns while cooling. You can also effect its color, creating intense rainbow colors, while cooling. This piece measures 44mm x 20mm x 16mm and was sourced from Brazil.
