Rare Brown Opal thunder egg (in the rough) from the base of the tribe's restricted area of the Mutton Mountains at Skookum Creek on the Warm Springs Indian Reservation in Central Oregon.

This location is the only known source of brown opal within the 3000 square miles of this rez. No one other than my tribal member husband and I know where it is located. It is our secret spot for beautiful, collectible rocks and gems. :)

Large 1/2 egg, sprayed lightly with water to show coloring
