A very LARGE specimen of natrolite matrix with SHARP, LUSTROUS, caramel-colored joaquinites to 2 mm in size spaced like a ribbon running the length of the piece. These are actually larger and sharper than average for the species. Now that I think about it, This could trim to make two equally good and more balanced miniature-sized specimens...but its so rare to find a large rich piece, I want to leave it intact. MUCH BETTER In PERSON.
