RM580   Cerussite

Lescure mine, Mayres, Ardèche, Rhône-Alpes, France

Recent mineral find and novelty at Sainte-Marie-aux-Mines 2013. A very rich group of prismatic cerussite crystals, with white color, translucent, brilliant, very acute and complex terminations and good size. With striated faces. Contrasting very aerial on the matrix.
The lead and silver mine of Lescure was worked in Roman times and there are documents from the late eighteenth century telling us about these mines. Although "serious" mining operations are confirmed from 1808-29 until its closure in 1951. These specimens are known in long crystals, and since the 90s had not been obtained pieces of this quality. Today the mine is closed and collapsed (Le Règne Mineral, 85, 2009).


Size: 7,5 x 4,6 x 3,2 cm.
Main crystal: 21 x 4 mm.
Found in 04-05/2013.

Fluorescent under long wave UV

RM682   Smoky Quartz

Talèfre glacier, Mont Blanc Mts., Chamonix, Haute-Savoie, Rhône-Alpes, France

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.
Found in 2012.

 

RM1115   Smoky quartz

Pointe des Periades, Glacier de Leschaux, Massif du Mont Blanc, Chamonix, Haute-Savoie, Rhône-Alpes, France

In this floater specimen we can observe a rich group of quartz crystals, one of them 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. It is not easy to find specimens from this Alpine quartz locality.
