This rare skorpion mine association piece is ex H. Soltau and retains its original number 345. What sets it apart is that the tarbuttite psm are chalcedony instead of fluorapatite, with a unique green color with grey botryoidal structures instead of the typical styled variants that you see.

The condition is superb.
