A cluster of several dozen intergrown Smithsonite crystals comprises this large thumbnail specimen. These crystals are generally in good condition, though several exposed ones are damaged, and do not exceed 0.2" (5 mm) in diameter. They have very good trigonal prismatic form that takes on the shape of a hexagonal bipyramid, though they are slightly warped due to their heavy intergrowth. All have an odd, coppery-red color that is actually caused by copper inclusions! Their luster is pearly and bright, and all are at least dimly translucent. There is no host rock present, and the piece is affixed to a beveled square acrylic base with a removable putty.
