RM2197 Pyromorphite with coronadite and quartz
Bedures Hill, Meredo, Vegadeo, Asturias, SpainAs M. Calvo indicates in his work (Minas y mInerales de España), in the area of Bedures hill (or Vidures), in the municipality of Vegadeo, there are several mining works, some of them very ancient, in which various lead mineral species have been described and among them, pyromorphite stands out. This piece we propose, found by chance in a mineral show far from the mine that saw it born, shows a matrix of milky quartz, with iron oxides and a black layer of coronadite in one side. We can observe also several crystals of green pyromorphite on the surface. Some form divergent aggregates, others isolated, but with an intense green color, with zoning in some of them. They show hexagonal prisms truncated by pinacoidal faces and parallel growth aggregates. A very rare specimen for this Spanish locality.
Size: 5.5 x 4.8 x 4 cm.

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.
