Vanadinite    J.C. Holmes Mine, Santa Rita Mountains, Temporal Gulch Area, Wrighton District, Patagonia, Santa Cruz County, Arizona. 7.4 x 5.1 x 2.5 cm. I believe this is relatively new material... well formed crystals with a satin luster, in good coverage on an attractive specimen. The crystals are exceptionally large for this material. There are a few places with tiny crystals missing but given the size of the crystals and display qualities of the piece, I believe it superior toothers I have purchased and seen available. $75
