Chrysotile in Serpentine (Antigorite) (rare locality specimen)

Item Description

A rarely seen specimen from the Montville Serpentine Deposit, in Morris County, New Jersey featuring veins of golden-beige colored, chatoyant Chrysotile, running through greenish-yellow, translucent Serpentine (Antigorite) in limestone matrix. This is the ONLY specimen of this material that we've had to offer from this well-known historic locality that dates back to at least the 1930, where it was mentioned in James Manchester's book, "Minerals of New York City & Its Environs". A really cool esoteric specimen that would make a great addition to any suite of New Jersey minerals or specimens from the Serpentine Group.
From the collection of William ("Bill") (1927-2006) and Anne (1928-2021) Cook of Cleveland, Ohio (#5495) with a label from John Ebner who stated it was collected on March 22, 1970. This husband and wife duo were actively involved in the mineral world for many decades. Bill was a PhD geologist, and Anne was a mathematician, and they both were very serious mineral collectors. Bill served for many years as adjunct curator of mineralogy at the Cleveland Museum of Natural History, and Anne was inducted into the Micromounters' Hall of Fame on October 12, 2019. Both Bill and Anne, at various times, served as president both of the Mineralogical Society of Cleveland and of the Micromineral Society of the Cleveland Museum of Natural History. The rare barium lithium beryllium phosphate Wilancookite was named in their honor in 2015.
