Brilliant, lustrous Emerald-green mass of well-formed crystals on minimal matrix. From the world class find about 8 years ago at Milpillas, these were huge news in the mineral world at that time. They have since become very scarce on the market in such quality. The crystals reach over 1.2 CM long and are fairly stout so the specimen is not as fragile as many were. The style and esthetic feel of these Brochantites are unlike any others worldwide, this is a very choice example.

A sizable thumbnail of Brochantite from the earliest find at Milpillas. This has the mixture of very slender hairlike crystals and the more stout, thicker ones. Excellent color and condition. We saw very few good thumbnails sized pieces of Brochantite from Milpillas as most were quite large. The Brochantites found at this locale were quickly hailed as world-class and set new standards. This small piece is a choice example that is a perfect, tiny part of this important discovery.
An extraordinary and important old specimen of Brochantite from Chuquicamata, Ex Schortmann's and Immer Cook collection. The original label dates this to 1948-52, and by far it the best specimen I know of from this famed mine. This is certainly a serious contender for the best of specie outside of the 2016 Milpillas find. Even compared to the Mexican specimens this is a very significant stout cluster. The largest crystal is huge, 4.6 CM tall and quite thick. Close exam of the specimen finds a few slender needle crystals which are more typical of the specie. Under good magnification (40x) a few specks of blue that can be Krohnkite, Bellingerite or Aubertite etc are visible. There are areas of contacting making some rough edges but very little damage. A world class Copper secondary specimen.

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.
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 incredibly 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.
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.
