Perhaps best known as the lustrous black mineral often associated with Benitoite, Neptunite is only very rarely faceted. Though always appearing black, these are actually extremely dark red. What makes this example so nice is that some of the red is actually visible as reflections of surface features in the stone. On the rare instances we have seen these cut, that is almost never the case. Very well done and quite difficult to obtain this nice.
