Straight from the hand of Nature, and Scott Resources, comes this boxed collection of (15) 1" to 1-1/2" fluorescent mineral specimens, such as hackmanite, turritella agate, aragonite, travertine, willemite, resinous coal, selenite gypsum, fluorite, calcite, scapolite var. Wernerite and fossil algae. All are very interesting, and a few colors really pop under ordinary blacklight -- but we have to admit that today's fluorescent paints and laser shows have spoiled us for the more subtle glow of a rock. Buy these for their educational value, not their dramatic display.
