This specimen possesses the largest Hopeite crystals that I have yet seen in my travels. The specimen consists of a flat, rusty-brown base of an unknown mineral that has a distincly botryoidal shape. On one edge of this host rock rest at least 15 Hopeite crystals which appear to be in excellent condition; only one that I can see is damaged and incomplete. They are in a complex orthorombic prismatic form and appear to have a lopsided hexagonal cross-section. They have a pale, rusty-red coloration and a dull, pearly-to-waxy luster, and are dimly to moderately translucent. The largest of these crystals measures about 0.4" (1.0 cm) in length and about half that in its other dimensions. It is attached to a small, flat acrylic base with a silicon-based soft glue.
