This hand specimen consists of a brown base rock on which rest several Uranophane sprays. These sprays are generally in good condition and each contain many fine Uranophane needles that reach up to 0.5 (1.3 cm) in length. These crystals are too fine to effectively study with a loupe, but likely have reasonably good monoclinic form. Their bright yellow color and pearly luster are standard for the specie. All are translucent at best, and likely opaque. The shallow hollows in which they rest are lined with what appear to be tiny quartz crystals, and likely some dark oxide compound.
