Brochantite
stock #AX-3-413
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
3.3 x 2.3 x 1.6 CM (thumbnail)
price: $260


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.

Azurite on Malachite
stock #AX-3-045
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
3.7 x 2.6 x 1.6 CM (small miniature/ large thumbnail (toenail))
price: $1350
new year 2021

From the great finds at Milpillas, this is a very fine small miniature in perfect condition with excellent esthetics. The Azurite crystals stand up from the contrasting green Malachite which covers a thin shard of matrix. These are translucent on the edges with a brilliant blue. A few tiny spots on the Azurites show Malachite alterations and the overall luster is very bright. With a close exam or under magnification the crystals are seen as compound prisms made from aligned crystals in an almost rosette structure. This piece is more impressive in person, and has a lot of display impact for its size. When Milpillas was active it produced lots of good Azurite and also a few really great pieces. Finding an above average specimen with rich color contrast in perfect condition (and at a fair price) was never easy. This is that sort of piece.

Azurite
stock #AX-3-104
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
2.7 x 1.6 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $300
new year 2021

A highly lustrous, bright deep blue cluster of Azurite crystals showing complex edge and face modifications. In excellent condition as seen this has a few tiny bits of Malachite alterations but is nearly all brilliant Azurite. From early finds at Milpillas, this is unusual since the crystals are complete, doubly terminated and without any matrix.

Azurite with Malachite - curved faces
stock #AX-24-058A
Milpillas Mine, Cuitaca, Municipio de Santa Cruz
Sonora, Mexico
4.6 x 2. x 2.1 CM (miniature)
price: $880


Milpillas Azurite with well defined crystals having top luster and electric blue color. Far more striking in person, these crystals show the curved faces that are distinctive from the last pockets found. All are clustered in a complex array and the specimen displays well from many angles. In exceptional condition, a few bits of Malachite are present but this is nearly pure deep blue Azurite. Thanks to the large finds that were preserved from this mine it is possible to find superb Azurites for a a cost far less than it was 10 years ago which is not at all normal in the mineral world.

Azurite
stock #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.

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 #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.
