Fluorite sur Rhodochrosite

Incontestablement, il s'agit d'un gisement extraordinaire, tant par la beauté des spécimens de rhodochrosite que par l'association avec de la fluorine. Le numéro hors-série du Mineralogical Record qui lui est entièrement dédié présente des spécimens dignes de faire pâlir les plus néophytes...

"Découverte en 1873 et exploitée pour son filon d'argent, la mine Sweet Home située près d'Alma, Colorado, est aujourdh'ui connue pour ses cristaux magnifiques de rhodochrosite, reconnus comme les plus remarquables du monde.
Pendant plus de 90 ans, la mine a été exploitée de manière intermittente avec un succès modéré en tant que mine d'argent, avant de fermer en 1967. En 1991, elle a été réouverte, non pas pour l'argent, mais pour les specimens minéralogiques et s'avera être incoyablement prolifique.

En plus de la rhodochrosite, l'espèce de collection la plus importante à la mine Sweet Home, est la fluorite, tétrahédrite/tennantite, pyrite, quartz, sphalérite, galène, hübnérite, bornite, fluoroapatite et chalcopyrite.Beaucoup des plus remarquables specimens de la mine offrent des associations avec ces minéraux.

Avant de fermer, en 2005, la mine produisit des centaines de specimens de rhodochrosite de top qualité, dont beaucoup sont dans les muséums et dans des collections minéralogiques privées."*

Stunning large plate of Rhodochrosite rhombs with Quartz, Pyrite, and Tetrahedrite! I don't think I need to tell anyone how rare plates of this size are today. Just attend a mineral show and the specimens you see can be counted on one hand. This plate is covered with gemmy red Rhodo crystals and some associated minerals for contrast. The largest crystals are around 2 cm but most average 1.5 cm in size. The plate is in excellent condition with only a few bumps here and there which I will mention for accuracy. There are the normal incomplete crystals around the trim line of course and at about 2 o'clock a rhomb has a small contact where it was touching matrix. None of these detract in the least from the dazzle of this gorgeous red plate and aren't even noticeable without close inspection. This is the first large plate I've offered in a couple of years and they go very fast. If you need one for your collection, here it is! From the Millennium Pocket, Fluorite Raise, Sweet Home Mine, Alma, Colorado. Measures 12 cm by 14 cm in total size. © Kevin Ward and The Mineral Gallery

An amazingly beautiful specimen from the Nate's Pocket, Mini King Raise, Sweet Home Mine, Alma, Colorado. Measures 6.2 cm by 10.4 cm. In case you're wondering, the Fluorite near top center measures 2 cm and the Rhodo is 1.5 cm! © Kevin Ward and The Mineral Gallery
