Wulfenite     Glove Mine, Santa Cruz County, Arizona.  Ex. Carolyn Les collection.  Very large, transparent yellow crystals compose this 4.3 x 1.6 x 1.6 cm grouping.  The backsides are coated by a brown material making them look translucent instead of transparent.  Minor edge chipping on a couple of crystals but overall in very good condition.  These crystals are very thin and fragile.  A very nice example and unusual for the large crystal size.  $220
