A metallic, mirror bright, crystal of silver colored molybdenite, 3.5 cm in length, is embedded in massive, milky quartz. I believe that this is a rare occurrence....I certainly have not seen another for sale! And, it happens to be fairly good, as well. According to Arizona collector Les Presmyk, "Thirty years ago, a small quartz dike south of Cleator, Arizona was found to contain intermittent pockets of molybdenite. This is an area of the state that contains numerous quartz veins and dikes but this is the only one that contained molybdenite crystals. Typical crystals were under 1 cm so this is large for the locality. The digging was difficult and the pockets were sporadic so good specimens from this locality are uncommon. There was only one specimen in the Urish collection so this is one Harold traded for rather than collecting himself. I would think a must for those molybdenite or sulfide collectors out there!"
