Prehnite (ex Rich Kosnar Collection)

Item Description

A nice display specimen of Prehnite from the famous Millington Quarry in New Jersey. This locality is probably best known for its amazing Pectolite specimens, and although Calcite and Prehnite are fairly common, you don't see a lot of pieces on the market, especially now that the quarry is closed. This piece hosts a pair of spherical groups of greenish-yellow Prehnite measuring up to 2.0 cm free of matrix. If you look at the back and base of the piece, you'll see there are a couple of "flat" edges on the spheres of Prehnite, which are actually "casts" where thin tabular crystals of Anhydrite once grew, and were eventually dissolved away. A really attractive and fine quality example of these beautiful Prehnites. From the collection of Richard A. Kosnar, with a label from Frank Imbriacco which states the piece was mined in October of 2006. Very nice for the locality, and as I said, hard to find now that the locality is closed.
