A single cluster of radiating Boltwoodite needles rests on the sandstone base of this hand specimen. The cluster measures 0.6 x 0.4 x 0.2" (1.5 x 1.0 x 0.5 cm) and is in excellent condition, showing very little damage. Its crystals are quite fine, but likely have a good monoclinic form. Their deep yellow color and silky to pearly luster are standard. The cluster rests on a bed of tiny calcite dogtooth crystals. Like all uranium-bearing minerals, this piece emits radiation that is easily detected with personal radiac equipment or a Geiger-muller counter.
