Miniature, 5.2 x 4.2 x 2.7 cm
Roughton Gill Mine, Caldbeck Fells, Cumberland, Cumbria, England
Ex. Lindsay Greenbank
Nestled in a vug of massive copper-rich ore are lustrous, translucent, dark green, crystals of brochantite, to 3 mm in length. The prismatic crystals exhibit gemmy, emerald green highlights. Although the affixed Behier label states Keswick, Cornwall, the specimen is actually from Roughton Gill (near Keswick, Cumberland, now Cumbria), and was perpetuating an old error by a collector who, like I would have, would naturally assume that any English brochantite MUST be Cornish! Ex Jean Behier collection. According to Greenbank, this specimen once had an accompanying Bryce Wright label as well (as documented in the book, Minerals of Northern England).
