Prehnite (ex Brian Kosnar Collection)

Item Description

The now closed Millington Quarry existed for over 100 years (it opened in 1895). Starting in the late 1970's the quarry reopened and started producing a large number of some of the most interesting and beloved specimens from this incredible quarry. This is one of the most famous trap rock quarries in New Jersey and it perhaps its greatest claim to fame are its spectacular Pectolite specimens, along with some impressive Prehnites. To be honest, this is one of my favorite trap rock localities in New Jersey due to the quality and quantity of pieces that came out in such a short period of time. This particular pieces hosts beautiful green color, sparkling radiating spherical aggregates of Prehnite with minor Calcite creating an attractive large thumbnail / toneail display piece. If you flip the piece over, you will see a small hollow cavity on the back of the larger Prehnite "ball" which is could be a "cast" where a crystal of Anhydrite once grew and was later dissolved away. Now that the mineralized zone at Millington is finished, you will not see any more of these beautiful specimens on the market anymore. A great trap rock display specimen from this significant New Jersey locality. The piece was formerly in the collection of Brian Kosnar, and comes with a label from New Jersey collector, Frank Imbriacco.
