Rosell Minerales
RM1949 Graphite
Tres Hermanos mine, Pilotuerto, Tineo, Asturias, SpainNowadays, graphite specimens from this classic Asturian locality are very difficult to be found. These specimens show contiguous columns, with greasy luster and defined hexagonal forms. The crystal habit of natural graphite in most cases is determined by its highly anisotropic, layered structure. However, anomalous habits of graphite,determined not only by its structure, but also by the peculiarities of the growth environment, are frequently encountered, and optimization of the space available when solidifying forming columns.
Size: 6.5 x 3.0 x 3.0 cm.
Found in ±1985.
