This is a large thumbnail, toenail, or small miniature as you prefer to call it. It is a sparkling, jewel-like copper cluster that is 3-dimensional and exquisitely crystallized all around. In fact, it is a floater, with no attachment points. The shape is overall somewhat like a children's toy "jack," in that it sits at many angles. The crystals are to 1 cm, and have a natural, shimmering patina that is very distinct for this find.
