The bone wedge weighs about 1 lb 8oz. And is about 5.75 inches across at the widest measurement x 4.25 inches x 1.75 inches deep. The marrow pattern is distinct on both sides with a rind pattern along the back. A truly unique and attractive solid specimen and it is completely natural with no coatings.
