Rosell Minerales

Epidote specimens from this area of Mont-Blanc are not at all common. This specimen was purchased by Joan Astor in Chamonix. It is an idiomorphic crystal, of a good size, with well-defined faces, except for one in the upper part that is fractured. We can also observe growth fissures. This specimen has its history since it was acquired from Francesc Garcia, one of the referents of Catalan mountaineering.

Size: 4 x 2.8 x 1.3 cm.
Found in ±1975.

Col. Joan Astor (Barcelona).
Classic locality

A rich group of quartz crystals, brilliant, transparent and with a very delicate and aesthetic smoky tone. They show well-defined prism and complex forms in top faces. They are disposed on a rocky matrix with albite. Talèfre glacier is located in the heart of the Mont Blanc massif.

Size: 9.5 x 7.3 x 4.6 cm.
Main crystal: 23 x 8 mm.

In this floater specimen we can observe a group of quartz crystals, two of them clearly dominant, with well defined faces and edges. We see a well-developed prism with rhombohedral terminal and trapezohedron faces. Transparence and brilliance are both excellent and with a very uniform smoky tone.

Size: 6.2 x 4.7 x 4.3 cm.
Main crystal: 35 x 28 mm.

Size: 7.2 x 7.3 x 3.8 cm.
Main crystal: 74 x 41 mm.
Found in 2015.

In this specimen we can observe a group of quartz crystals, one of them dominant, with well defined faces and edges. We see a well-developed prism with rhombohedral terminal faces and a possible small trapezohedron face. Transparence and brilliance are both excellent and with a very uniform smoky tone. It is not easy to find specimens of alpine smoky quartz at reasonable prices, without nicks, and less with this size.

Size: 9,2 x 9,0 x 6,0 cm.
Main crystal: 6,8 x 4,3 cm.
