Cuprite on Dickite
stock #16.1-639
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
7.1 x 2.9 x 2.5 CM (cabinet)
price: $650
Dec 2018

A shard of breccia bedrock is thickly covered with white Dickite that holds clusters of sharp bright red Cuprite crystals. The Milpillas mine is world famed for its great Azurites but several other Copper species are also first rate at this mine. The Cuprite on this piece is epitaxially oriented and has clean dark red color with bright luster. The individual crystals are sharp and damage free, all are transparent and could be faceted. Well above average quality for the find, the crystals are3 complete, well formed sharp and have classic form, unlike the flattened and distorted Cuprites that are more typical from here. Not just a locality piece, this is a choice displayable specimen that is impressive in person.
Azurite
stock #18-AX-3-288
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
3.7 x 2.2 x 1.3 CM (miniature)
price: $340
Late Summer 2018

A nicely perched deep azure-blue crystal on contrasting matrix. The habit is typical from Milpillas in the early finds and looks fine from several angles. Milpillas was such a productive locality when the Azurites were found that they are still very affordable. This piece is well above the average for quality and esthetics as seen. No damage but some small contacting that is not on the logical display angles. Very choice luster, sharp and with very bright color especially when well lit.
Wulfenite -classic
stock #13.1-079
San Francisco Mine, Cucurpe
Sonora, Mexico
3.2 x 2.5 x .6 CM (small miniature/ large thumbnail (toenail))
price: $725
Late Summer 2018

A large complete crystal (with several coating both sides) in fine condition from the famed finds at the San Francisco Mine, Sonora, Mexico. Colorful and transparent, the luster is glassy and the lack of damage is remarkable. These Wulfenites with large crystals like this were all collected more than two decades ago. They were (and are) very fragile, so fine complete larger crystals were uncommon. A choice and showy crystal, these have gotten very expensive and harder to find.
Azurite on Malachite
stock #18.1-406
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
2.4 x 2.1 x 1.7 (thumbnail)
price: $160
Late Summer 2018

Pretty thumbnail of lustrous Azurite on contrasting green Malachite. There were many Milpillas Azurites in the big finds that ended 3 years ago, this resulted in great opportunities for collectors to get very good pieces at abnormally low costs. This is such a piece with the bright color, sharp form and fine contrast. In excellent condition, looks good front and back.
Brochantite- mix of needles and thicker crystals
stock #18-AX-224
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
4.6 x 3.2 x 2.3 CM (miniature)
price: $650
Worldwide mix summer

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.
Azurite-
stock #18.1-AX-24-298
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
3.8 x 2.8 x 2 CM (miniature)
price: $450
Spring update

Undamaged, bright luster, intense deep blue and esthetic, a fine small miniature from Milpillas. The crystals on this piece show both classic sharp prismatic faces and the large curved faces that have a more satin luster. Recognized as one of the greatest mineral finds of all time, this mine produced many good specimens, so the prices have been relatively low for this sort of quality. Better in person and a great value for the most desirable "electric" color.
Cuprite- gemmy red crystals
stock #16.1-640
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
6 x 4.4 x 1.7 CM (cabinet)
price: $520
Pre Holiday 2017

A well formed, bright stack of Cuprite crystals from the great Milpillas mine, better known for world class Azurites. This find of Cuprites created a big stir 2 years ago, but few were undamaged or had crystals much over a few millimeters. This piece is far better than average, in excellent condition damage wise and the crystals are stacked in an esthetic epitaxial arrangement. These octahedrons all will glow bright red with focused light passing through them, the photos here are only made with typical display lighting, so as not to be misleading. When these were first found the prices being charged were incredibly high, this is a lot more reasonable, yet a fine quality piece, by comparison a really good value.
Azurite -textbook form crystals
stock #17.1-AL- 24-299
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
3.9 x 2.1 x 1.4 CM (miniature)
price: $1050
new june 17

A top esthetic Milpillas Azurite presenting an elegant cluster of perfect, sharp, crystals on contrasting matrix. Not a typical specimen, this form and habit are quite rare from Mexico. Textbook prismatic crystals reach 2 CM in size and are undamaged. Milpillas produced many great specimens while it was producing but specimens like this were never common. Choice.
