A huge plate of purple creedite, with crystals to 3.8 cm. In fact, it is the single largest creedite of this color that I have seen, from all the finds at Mexico or Kazakhstan, of any high quality. It is dramatic and 3-dimensional, more so in person. It is also very much more deep purple than all but the very finest of Mexico material (and those have smaller crystals on smaller specimens, in any case). A significant rarity from the collection of Marc Weill, obtained by me via exchange. I first saw the specimen in the late 90s and have remembered it ever since. To this day, I have not seen better.
