Mimetite on Arsendescloizite

Item Description

A now seldom seen specimen from a discovery in 1988 (brought to market in 1989) that features beautiful radial groups of soft yellow colored Mimetite and rich green Arsendescloizite. This large miniature / small cabinet sized piece hosts many "balls" of Mimetite which actually range in color from a soft yellow hue to a light yellow-green color, which are sitting atop botryoidal, waxy groups of strong green colored Arsendescloizite, on oxidized matrix. I haven't seen many of these over the years, and if you collect secondary ore minerals, or specifically pieces from the Ojuela Mine, don't miss out on this attractive piece from a few decades ago. From the collection of William ("Bill") (1927-2006) and Anne (1928-2021) Cook of Cleveland, Ohio (#6966). The back of the label states that this piece is from the Klimetz Collection.

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.
