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. This particular pieces hosts a few lustrous, vibrant, rich green color radiating spherical aggregates comprising dozens of "clamshell"-shaped crystals of Prehnite on minor basalt. The largest sphere measures 3.3 cm across, and has an indentation which is actually crystallized, and not damaged. 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.
