White Buffalo Turquoise is quite unique and rare. It was discovered in the Dry Creek Mine north of Auston Nevada in 1993. Because of its hardness, it was sent to be assayed and it was in fact White Turquoise. The chemical name for Turquoise is Aluma Phosphate which in its pure chemical state is white. Turquoise takes on color via an intrusion of either copper (blue color) or iron (green color). To date, no other vein of gem quality white turquoise has been discovered anywhere else in the world. Because White Turquoise is as rare as a white buffalo, the Indians call it "White Buffalo" Turquoise. The White Buffalo Turquoise is itself considered sacred and powerful. The jewelry-making is an honoring or tribute to the "White Buffalo".  Hoop Earrings are 1"
