Sulfur (doubly-terminated) (RARE locality specimen) (ex Bill and Anne Cook Collection)

Item Description

We've only had a handful of Sulfur specimens from this obscure locality, and this piece is the best individual crystal that we've had to offer. An impressive, sharp, very well-formed, lustrous, translucent, beautiful glowing yellow colored crystal, free of matrix. The crystal is not only doubly-terminated, but it's nearly a complete "floater" as it's crystallized on all sides, with only one small point of attachment on the back. You don't think of Nevada as a good Sulfur crystal producer, but this piece certainly breaks the mold and is a much better than anything else we've seen from the Alum Mine. If you collect native elements, US minerals or you just appreciate fine crystals from lesser-known locales, don't miss out on this one. From the collection of William ("Bill") (1927-2006) and Anne (1928-2021) Cook of Cleveland, Ohio. 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, and Anne was inducted into the mi The rare barium lithium beryllium phosphate Wilancookite was named in their honor in 2015.
