A vug of well protected Brochantite crystals ex John Marshall collection that has an excellent provenance. John bought this from Johnathan Smith (NYC mineral dealer) in Feb 1994. Jonathan had obtained this from the Alan Green collection who had gotten this from the Schortmann brothers at their famed sale in NYC in 1950, at the Hotel Lexington. This is the period where the Schortmans were selling minerals collected by Ed Over and Arthur Montgomery. All the original labels for this are included. In good condition, a cute Utah Copper specimen with pedigree.

Bright green Brochantite crystals standing on end in a dense cluster. The matrix is mostly Brochantite as well, and formed of packed needles. The larger, thicker crystals are quite robust and these have a fine silky luster. From the epic finds at Milpillas, these Brochantites are one of the great surprises from the oxidized zone of this incredible Copper mine.
Brochantite- (rare stout crystals)
stock #Alec-3-481
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
4.9 x 3.7 x 3.9 CM (miniature)
price: $775


A well formed and undamaged specimen of the "stout" crystal habit found about 4 years ago at Milpillas. This locale is now world famous for some of the best Azurites, and the very best Brochantites ever seen. The Brochantites were mostly of the delicate "hairy" or fuzzy type, which were beautiful but incredibaly fragile. Only a few of the thicker crystals on matrix came out. The very best pieces sold quickly in the 5 and 6 figure range, few were available for collectors of "normal" means. This is one such- an excellent miniature example that is both esthetic and affordable. The largest crystal is 2.5 CM long and all have excellent luster.
Brochantite (exceptional accicular crystals)
stock #10.1-260
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
6.6 x 4.6 x3.3 CM (cabinet)
price: $1400


An extraordinary, delicate, electric green brochantite from what may be the best discovery ever of the species. In person the color is an intense emerald green deeper than can be rendered on most computer monitors. Perfect condition, strong esthetics and intense color make this piece stand out in any display. There have been only a few small pockets of Brochantite over the past few years at Milpillas which is far better known for incredible azurites. There have been very few fine specimens in these finds, and none recently. Without a doubt these will be regarded as some of the best of the specie ever seen, and are a fine affordable investment. This specimen can be shipped with special arrangements but it is far safer to deliver in person at a major show or by other arrangement.
