White Buffalo Stone

The material is mined in Nevada; the White Buffalo claims of the Otteson family, associated with Tonopah, are recorded by the Bureau of Land Management in the Battle Mountain district, Esmeralda County. The Japanese retailer Pascle also lists Arizona and defines its own White Buffalo as the nearly hematite-free white part of "Wild Horse", a different usage of the name.

Genuine turquoise is a copper phosphate, and its copper should prevent a snow-white color, so a white stone sold as "white turquoise" or "White Buffalo Turquoise" is better treated as White Buffalo Stone. Over the years the material has been variously reported as calcite, calcite with opal, howlite, magnesite and planerite; only laboratory methods such as X-ray diffraction or infrared spectroscopy establish what a given piece is.
