37417: Quartz - $20 Mine à Breton, McArthur mines, Potosi Barite Mining District, Washington County, Missouri Small cabinet - 6.8 x 5.7 x 5.7 cm 112 grams Specimen status: Available Send an email with specimen number to order Mounds of opaque but sparkling quartz
crystals. The original matrix is now absent, resulting in
a hollow core, so maybe this is an epimorph...? An old
(discovered about 1773) but rather obscure locality, for
which Mindat lacks any specimen photos. Self standing and
in excellent condition.
