Wulfenite      San Francisco Mine, Cerro Prieto, Cucurpe, Cucurpe Municipality, Sonora, Mexico.  Ex. Caroline Les collection.  This competition sized thumbnail specimen is 2.7 x 2.6 x 1.3 cm with a large display crystal having a couple minor crystals diverging from its base on the front and backsides.  Everything visible when displayed is damage-free but two of the small crystals on the back are damaged.  The crystals have a beautiful coloration, excellent luster, and impeccable crystal form.  The crystal stands on edge as seen.  This is an exceptional example of this material (which is becoming difficult to get in good specimens) for those who seek fine smaller pieces.  $250
