Danburite is of course well known for Charcas, and in fact may be the best-of-species locality. We have seen many small danburites that are thumbnail sized. However, THIS is a competitive thumbnail with style, and a very rare and contrasting association with a 1 cm bornite crystal hanging off the side! Unique in my experience, and this makes it something much more fun to show than a typical single crystal standing alone in a mount. From the award-winning thumbnail collection of Sharon and William Panczner, author of the book Minerals Of Mexico, and last seen and exhibited in the 1960s
