This is a true “Bisbee classic”, featuring sharp, undamaged malachite after azurite crystals to ~4 cm. forming a divergent spray on brown gossan matrix. A historic specimen, coming originally from legendary early 20th century mineral dealer Martin Erhmann, who obtained it in trade from this Smithsonian in Washington D.C. It then went to the noted collection of Bill Severance in West Grove, Pennsylvania. A wonderful and classic Bisbee piece, with super aesthetics and zero damage. Mark Cross photo.
