Ojuela Fluorite and Milpillas Cuprite

As prolific as Mina Ojuela has been over the years, fluorite was never common at this location.  The specimens on this page come from a recent find, and incorporate the iconic limonite matrix that we have all become so accustomed to seeing on species like adamite, mimetie, rosasite and aurichalcite, what I would consider to be the staples of Mina Ojuela's production, with another species: fluorite. 


There is also a small selection of cuprite specimens from Milpillas-- none of the examples I have seen from the location have been especially notable compared to pieces from Namibia, Arizona, or even Russia, but these are at least priced more reasonably than nearly identical pieces I've seen elsewhere.

MFC01 Fluorite
Mina Ojuela, Mapimi, Durango, Mexico
7.0x 4.4x 3.4 cm
$385

A very nice and uncommon example of fluorite from Mina Ojuela, on a limonite matrix.  As prolific as this mine has been over the years, fluorites have never been very common from there.  This is a particularly nice example, with the main crystal showing a good degree of transparency.

Unusual and hard to find material.









MFC02 Fluorite
Mina Ojuela, Mapimi, Durango, Mexico
8.6x 6.5x 3.5 cm
$270

A  nice and uncommon example of fluorite from Mina Ojuela, on a limonite matrix.  As prolific as this mine has been over the years, notable for the countless adamites, mimetites, aurichalcites, hemimorphites, etc. that have kept many wholesalers going,  fluorites have never been very common there.  

This piece hosts two crystals with lightly etched surfaces.

I have not tested these specimens individually, but many show a reddish-pink fluorescence.

***Please note, these do exhibit a degree of fluorescence, so the color of these specimens varies with lighting, being more vibrant in sunlight, and somewhat more of a dark grape-jelly purple under incandescent, meaning that the contast between the crystal and the matrix may not always be as good as shown in the pictures, which were shot under optimal conditions.  Also, I suspect some of these have had oil applied...

MFC13 Fluorite
Mina Ojuela, Mapimi, Durango, Mexico
3.2x 2.1x 1.7 cm
$85

A nice toenail sized specimen of fluorite from Mina Ojuela.  As prolific as this mine has been, fluorite specimens have remained something of a rarity of the mine.

2.7x 1.8x 1.5 cm
$100

A nice thumbnail sized specimen of fluorite from Mina Ojuela.  As prolific as this mine has been, fluorite specimens have remained something of a rarity of the mine.  This is a very well balanced thumbnail example of this hard to find material-- not perfect, but displays exactly as shown.












MFC15 Fluorite
Mina Ojuela, Mapimi, Durango, Mexico

A nice specimen of fluorite from Mina Ojuela.  As prolific as this mine has been, fluorite specimens have remained something of a rarity of the mine.  This one has a dark purple cube with surface etching, on  limonite matrix.  Please note, many of these are fluorescent (I have not tested this piece however to see how strong) and there will be a difference in perceived color when viewed in day light vs. incandescent light.








MFC18 Cuprite
Milpillas Mine, Cuitaca, Sonora, Mexico
11.2x 6.3x 2.0 cm
$385

A nice specimen of cuprite form the Milpillas Mine, hosting numerous flattened crystals on a white matrix.  These have been really expensive regardless of whether or not they have decent color (these look metallic)-- I think it has something to do with them being from Milpillas, as for a while anything from there seemed to carry a premium.

In any case, this is a relatively good representative specimen, of decent size, and what I think is not a bad price.

In any case, this is a relatively good representative specimen, at what I think is not a bad price.  

**PLEASE NOTE: this does NOT look red in person, the reddish hue is a result of the strong lighting.  In person, the cuprite crystals will look dark and metellic.

Milpillas Mine, Cuitaca, Sonora, Mexico
2.5x 2.35x 1.0 cm
$135

A nice thumbnail specimen of cuprite form the Milpillas Mine, hosting a few flattened crystals on a nicely contrasting white matrix.  The main crystal is contacted on the right side, but it displays exactly as shown.

These have been really expensive regardless of whether or not they have decent color-- I think it has something to do with them being from Milpillas, as for a while anything from there seemed to carry a premium.

In any case, this is a relatively good representative specimen, at what I think is not a bad price.
