A rare Pennsylvania locality specimen – these are sharp, transparent, brilliantly lustrous quartz crystals (up to 2.4 cm) from the Reading Anthracite Co. coal mine at Wadesville. The crystals have formed a vug within what would have originally been a larger cavity – the “roof” of the vug is is fully crystallized on top (away from the opening) and also downward into the vug itself. In excellent condition, with only very minor nicks. From the John S. White Pennsylvania Collection, he acquired it from Robert Fender. Likely a relatively older specimen (the mine was opened in 1961), with an old catalogue number affixed. A beautiful piece in its own right, and eye-opening given the locality!
