Pyrite

ID: 6011

A floater group of intergrown,  silvery/golden pyritohedrons of pyrite in an compact formation, with a small group of additional crystals riding piggyback. Very cute TN!

Azurite

A plate of super lustrous deep blue crystals of azurite 2 cm well exposed on a nicely contrasting matrix. Even though there is a lot of good Milpillas azurites on the market, few are in perfect condition (like this one) and on the white matrix that shows off the crystals brilliantly.

Azurite

Add to OrderNot checked

A spectacular group of very lustrous, deep blue azurite crystals with minor malachite. This pocket was 15 by 10 meters (but very narrow) and the specimens were attached to the wall by fibrous malachite, that’s why they resemble “floaters”. The mine owners cemented the pocket entrance with three trucks of concrete, but some had been collected prior to that and I was very lucky (being near the source) to have my pick of the best miniatures and TNS. Nothing of any significance has been found since the summer of 2013. As commonly seen with azurite, the photos do not  do the specimens justice.

Galena, Sphalerite and Chalcopyrite on Calcite

ID: 5755
Add to OrderNot checked

A group consisting of one main crystal of calcite with a couple of smaller crystals attached, as well as lustrous grey galenas, yellow orange gemmy sphalerites and minor chalcopyrite. Almost a floater but there is a minor attachment point at the base of the crystal. Excellent miniature.

Malachite

ID: 5741
Add to OrderNot checked

Tiny crystals of deep green malachite forming botryoidal, organically looking specimens with a very aesthetic and sculptural look with white matrix attached. A new find from this mine and possibly the best non pseudomorphous malachites that have come out of Mexico.
