Greenockite (ex Rich Kosnar Collection)

Item Description

Greenockite is a rather rare species, considering it has a very simplistic chemistry (Cadmium Sulfide). There are only a handful of localities in the world for fine crystallized Greenockite specimens, and the Summit Quarry in New Jersey is possibly be the best U.S. locality for the species (certainly the best in New Jersey). This locality opened in the early 20th Century, and produced a large number of Zeolites species and other associated minerals in its history. It sadly is now long gone, but thanks to collectors like Richard Kosnar, many good specimens now survive from this historic Quarry. This specimen was collected by Richard Kosnar in 1965 shortly after he had graduated from high school. He had almost exclusive access to the quarry at the time, and was able to collect some very unique and interesting Greenockite specimens over several years time. As a matter of fact, Richard Kosnar most likely collected more Greenockite specimens from New Jersey than any other collector, even many collectors combined. This piece is mounted in a perky box, and upon close examination, one can see a small (less than 1 mm), sharp, GEM quality, orange-honey colored thin hexagonal tabular Greenockite crystal on Prehnite matrix sitting in grey basalt. This specimen is 50 years old, and many New Jersey collectors do not have a Greenockite in their collections, so don't miss out on this rare historic specimen. Valued HIGHLY even for a micro, and these are passionately sought after by collectors. The last one I had in this size and quality, sold privately for $500.
