TK67T2: Fine “oldie” with a group of cuboctahedral crystals on matrix, some of them with very well marked spinel law twins, that display a good luster considering it is an ancient sample from a classic locality. The piece is from the collection of John Marshall. The collection card is lost, but the pedigree remains testified by the number of small labels on the back side.
