RM2441   Tetrahedrite-(Fe) with digenite, malachite and azurite

El Coriellu mine, S. Cosme de Llerandi, Parres, Asturias, Spain

Tetrahedrite crystals from this Asturian mine are well known and prized by Spanish collectors. In this sample we have tetrahedral crystals, one of them predominant, in which the tris-tetrahedron shapes seem to point. Good size and partially covered by malachite. X ray diffraction analysis (we will send to the buyer) has shown the presence of digenite associated with the alteration of the tetrahedrite. A classic.


Size: 3.1 x 2.7 x 2.5 cm.
Main crystal: 1 cm.

RM2071   Azurite

El Coriellu mine, S. Cosme de Llerandi, Parres, Asturias, Spain

Very rich specimen formed by several rosettes of tabular to lenticular azurite crystals, intense color and contrasting on the matrix, with quartz. Its origin is due to the alteration of the chalcopyrite and are disposed on a silicified limestone matrix. Very good piece for the locality.


Size: 8 x 5.4 x 4.4 cm.
