About the stone ... a lot of sellers call it White Buffalo Turquoise, but it is NOT turquoise in makeup though it was discovered in a turquoise mine in Tonapah, Nevada. The white stone is surrounded by black and brown chert which creates beautiful patterns and matrixing.

Howlite is very common and White Buffalo comes from only one mine in Nevada.
