RM344   Fluorite with quartz

Mina Emilio, Caravia area, Loroñe, Colunga, Asturias, Spain

The colorless crystals of fluorite from Emilio mine are well known and show a hyaline transparency. It is hard to capture their brilliance with the camera. This specimen shows a cubic crystal druse with forms of the trapezohedron at the vertices. With some inclusions. Few crystals show small notches on the edges, very common in Emilio fluorite crystals because of its sensitivity to temperature changes, but without affecting their beauty.
A
brilliant miniature!


Size: 4,9 x 4,2 x 2,4 cm.
Main crystal: 10 x 9 mm.

 

RM989   Barite with calcite

Moscona mine, Villabona area, Solís, Corvera de Asturias, Asturias, Spain

These specimens have given more than a headache. They have sometimes been cited as celestine from Moscona mine. This specimen shows a group of barite prismatic crystals very rich in faces, with the combination of various orthorhombic prisms and pinacoids. Transparency is excellent and with an amazing brilliance. They are disposed in a matrix with white crystals of calcite. Very few specimens in collections.
