10003 Mimetite, Dry Gill Mine, Caldbeck Fells, North and Western Region (Cumberland), Cumbria, England

Specimen measuring 5.8×4.1×3.5cm weighs just under 5 ounces. Ex Martin L. Ehrmann (d. 1972) on Fifth Avenue, who according to the Mineralogical Record Archive became America’s premier dealer in high-quality mineral specimens. While the label simply states Cumberland, England, obviously this piece is from the Dry Gill Mine at Caldbeck Falls.
