XM2480MAR

Group of Fluorite crystals, one of them clearly dominant, aerial and extraordinarily limpid and transparent, with predominant octahedron forms and well-defined faces and edges. Color centers give it delicate misty bluish purple tones. On the back, the main crystal exhibits figures of contact dissolution during growth. These Fluorite crystals are implanted in a matrix formed of Mica crystals.

XM2480NNC

As pretty from the front as from the back! On the front side we see a group of cubic and tabular Fluorite crystals, with the edges modified by dodecahedron faces, very clean, lustrous and transparent, of a delicate purplish color, while on the back face, apart from some Fluorite crystals, there are several scalenohedral crystals of Calcite, one of them clearly dominant. With the cleanliness and transparency characteristic of specimens from this deposit.

Group of cubic Fluorite crystals on a matrix formed by Calcite crystals, some of them with scalenohedron forms, very clean, between transparent and translucent, of a delicate violet color, with the edges beveled by dodecahedron faces. Gemmy and transparent as is characteristic of the specimens from this deposit.

XM2170MBR

A rarity. Groups of lustrous, isolated and arborescent Pyrite crystals that have grown on a Calcite scalenohedron formed by polycrystalline growths clearly developed at the top of the crystal. They are lustrous and snow-white in color, giving a beautiful color contrast with the Pyrite. A very unusual habit for the deposit.
