RM1829   Graphite

Tres Hermanos mine, Pilotuerto, Tineo, Asturias, Spain

Nowadays, 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.


Size: 6.0 x 3.2 x 2.9 cm.
Found in ±1985
