This prehnite is from the Lower New Street Quarry, Paterson, Passaic County, New Jersey, USA. This locale was a basalt quarry worked in the first half of the 1900’s. The rock formations contain interstitial spaces, vugs and voids that are worked occasionally by collectors seeking some of the over two dozen species of minerals found there including prehnite. Prehnite is a silicate mineral that contains the elements Ca, Al, Si, O, and H. This is a finger-like stalactite formation consisting of botryoidal crystal clusters of prehnite that formed off of a  calcite crystal matrix. It has a light green color and nice translucency under bright light. It measures 1 1/2 x 1 x 7/8 inches or 38 x 25 x 22 mm.
