Heulandite (ex Rich Kosnar Collection)

Item Description

The quarry at Upper New Street is over 100 years old (it opened in 1893). During the mid 1980's to early 1990's, there was a lot of collecting that took place between the Upper New Street and Lower Street Quarries in an area that is affectionately referred to by some as "Middle New Street". The majority of the specimens from this area are still labeled as being found at Upper New Street even though they were not found in the quarry itself. Nonetheless, this is one of the most famous Trap Rock quarries in New Jersey and is probably most famous for its amazing and unique Prehnite casts after Anhydrite (sometimes called "fingers" or "snakeheads"). Heulandite is not very common from New Street, and this is a very attractive Heulandite from this locality. It features dozens of beautiful, sharp, highly lustrous, pinkish colored, pearly, layered crystal groups of Heulandite associated with Laumontite and Calcite on basalt matrix. The largest Heulandite group measures 2.3 cm long. A great Trap Rock display specimen from this significant New Jersey locality.
