Hematite on quartz - Bernardstein vein, Tête du Violu, Sainte-Marie-aux-Mines, Haut-Rhin, France

Small lamellar crystals of hematite, shiny, scattered on a mamelinated plate of small white quartz having previously encapsulated other minerals (perimorphosis of a probable rhombohedral crystallization carbonate). The interior of this perimorphosis is covered with a veil with a metallic lustre.

An original type of crystallization compared to the great Vosges classics, resulting from a small discovery reported in the January/February 2012 issue of the magazine "Le Règne Minéral".
