Hell’s Canyon Petrified Sequoia Freeform Cabochon
Vvery limited supply of a material discovered along the Idaho Oregon border in the 1950’s. The pattern is outstanding and the polish is like glass. This one is full of tiny vugs that go all the way through and some are crystal-lined.
You won’t see much of this around; the person who acquired it has said supplies are almost gone.
Measures 27mm x 45mm. 1 inch = 25.4mm.
