Wulfenite    Glove Mine, Glove Mine Group, Cottonwood Canyon, Tyndall Mining District, Santa Cruz County, Arizona.  Ex. Caroline Les collection.  This is an unusual example from Glove having black primary crystals (to .6 cm) coated by second generation colorless, transparent crystals.  The piece measures 6.7 x 2.7 x 2 cm.  It is a long thin hollowed out specimen that may have been a mold over a now absent crystal.  There is no damage to this floater other than a tiny broken crystal on the very tip of the specimen that can be seen under magnification.  This is a small but very unique wulfenite specimen.  $300
