The polished Hubbard Basin petrified wood slabs from NV will vary some but will have a measurement of approximately 10" x 6" x 3/4" The polished slabs are in a triangular shape all cut from the same round of rough.  The slabs are a beautiful blue and white with some tan and a small amount of rose color. The replacement characteristics are clearly seen with minute bands very closely spaced together. The Rociprolap polish on the slabs make for an outstanding slab for display or any other project you can dream up.
