82 cts. White buffalo (Opalized Calcite). This is the original White Buffalo stone sold by the Otteson family for many years. It comes from the White Buffalo claims just north of Tonopah Nv. Owned by the Ottesons, this is the only known mine in the world that makes this exact mineral. This is the mineral that so many people have tried to copy, by dying, impregnating wax and plastics into Howlite, Magnesite and other minerals. This is IT! These mines are concidered all played out. They are no longer mined other than the rare scavanging through the dumps for missed pieces. All of the White Buffalo on this website are from Tom, Tony, Trenton and Danny Otteson's personal collections. Mined and cut by them. If you have any questions, feel free to email or call.
