A gorgeous specimen with an antique Ward's Science Establishment label dating it to pre-WWI in the early 1900s(per the Mineralogical Record label archives). Ward's was an active buyer at the time, but an even older (unidentified, calligraphy) label glued to the back indicates this may date to the earliest days of copper camp mining in Arizona. However, the pedigree aside, its just an incredible specimen with eye appeal due to the startling contrast of the (8mm) primary malachite crystals to the blue quartz underneath. It was, in Hauck's collection, a stunning blue quartz representative...but its more than a mere quartz in my book!
