|Turquoise gets its color from the heavy metals in the ground where it forms. Blue turquoise forms where there is copper present (most Arizona turquoise). Green turquoise forms where iron is present (most Nevada turquoise). White turquoise, where there are no heavy metals present, turns out to be rare. At Auntie's Beads, we pride ourselves on our unique selection of turquoise beads and pendants. We hope you find them beautiful and inspiring as well!
