EXCEPTIONALLY RARE old Cornish mimetite specimen, most likely from the mid to late 1800s, and very seldom seen for sale. This features a crystal to 1cm. Nothing compared to Tsumeb, but for English mimetites, this is a good one! It has been sight-validated by several English dealers at the Denver show and comes with a label from another English dealer. 3.6 x 2.5 x 1.2 cm
