Rhodonite, quartz, sphalerite, pyrite

Group of transparent, sharp, well-defined, bright pink rhodonite crystals, associated with more than a dozen colorless and bright quartz crystals, upon a matrix formed by brown to black sphalerite and minor pyrite. The entire specimen measures 53mm x 52mm x 40mm, and the main rhodonite crystals are approximately 10mm tall, 6mm wide, and 1mm thick. Mass: 112g. It comes from the 2007 find at the Chiurucu mine, where mining works stopped long ago, and not far from the famous Huanzala mine, in the district of Huallanca, Peru.

Overall size: 53mm x 52mm x 40mm. Main rhodonite crystal: 10mm tall, 6mm wide, 1mm thick. Mass: 112g.

From San Martín Mine, Chiurucu, Huallanca District, Bolognesi Province, Áncash, Peru.

A better photo from this specimen has been added here.

Rhodonite - CaMn₃Mn(SiO₃)₅, quartz, sphalerite, pyrite

This is, I hope, a better photo, now shot by myself, of the specimen previously featured here.

Group of transparent, sharp, well-defined, bright pink rhodonite crystals, associated with more than a dozen colorless and bright quartz crystals, upon a matrix formed by brown to black sphalerite and minor pyrite. The entire specimen measures 53mm x 52mm x 40mm, and the main rhodonite crystals are approximately 10mm tall, 6mm wide, and 1mm thick. Mass: 112g. It comes from the 2007 find at the Chiurucu mine, where mining works stopped long ago, and not far from the famous Huanzala mine, in the district of Huallanca, Peru.

The color of that specimen, the crystals being so thin, is highly variable depending on the screen settings and the kind of light: solar, fluorescent, led, halogen, incandescent... For making things easier I just used the fluorescent light I have in my showcases and then processed the image without increasing the saturation, unlike many professional photographers do.

Overall size: 53mm x 52mm x 40mm. Main rhodonite crystal: 10mm tall, 6mm wide, 1mm thick. Mass: 112g.

Wulfenite

A small cluster of zoned tabular crystals of wulfenite grown on a matrix made of iron oxides. Some translucency can be appreciated in many of the crystals.

The overall size is 62 mm x 54 mm x 32 mm. The largest crystal size is 9 mm x 9 mm x 3 mm.

From Ojuela Mine, Mapimí, Municipio Mapimí, Durango, Mexico.

This specimen is no longer part of my collection.

Super Wulfenite and great photo Carles, I am very fond of these "sandwich" habit crystals from the Ojuela.

Hi Carles,

I hope you are doing fine, always a pleasure to see something new here in your wonderful collection. This wulfenite from Ojuela is really amazing, a perfect specimen captured in a superb photo! Congratulations, a very fine addition to your collection.

Best regards

Rhodonite - CaMn₃Mn(SiO₃)₅, quartz, calcite, sphalerite

Group of transparent, sharp, tabular, bright pink rhodonite crystals, associated with several colorless quartz crystals, and some calcite, all upon a matrix formed by dark color sphalerite. From the 2007 find at the Chiurucu mine, where mining works stopped long ago, and not far from the famous Huanzala mine, in the district of Huallanca, Peru.

The color of rhodonite crystals, being so thin, is highly variable depending on the screen settings and the kind of light: solar, fluorescent, led, halogen, incandescent...

Overall size: 69 mm x 39 mm. Main rhodonite crystal: ~9 mm long. Mass: 84 g.

From San Martín Mine, Chiurucu, Huallanca District, Bolognesi Province, Áncash, Peru.
