Rosell Minerales

A very good size specimen formed by numerous lanceolated baryte crystals, with very good definition of faces and edges. Between transparent to translucent and with a yellowish tone with zoning. They are disposed very aerial on the matrix, with crystals of calcite and fluorite with honey tones. Fluorite is active under LW-UV light. An exceptional specimen for this classic Asturian mine.

Size: 12 x 11.7 x 11 cm.
Main crystal: 2.2 cm.

Fluorescent under long wave UV

Historically the most representative fluorite specimens from mina Moscona are yellow, recently some of violet tones have been collected. This ancient specimen is one of the few that appeared in the mine with this pink to purple color, with zoning. It is a floater, formed by growths of cubic crystals with faces with polysynthetic growths, very brilliant and translucent. They are partially covered with sharp tabular barite crystals, between transparent to opaque on the outer edges. No damage, good size and fluorescent (UV-LW). A very unusual piece for this classic Spanish mine, from a former German collection.

Size: 16 x 14 x 6.5 cm.

Fluorescent under long wave UV

Rich group of fluorite crystals, cubic, transparent and very brilliant. With a yellow color with greenish tones. They are partially covered by snowy white rhombohedral curved dolomite crystals. From a classic Spanish mine.

Size: 7.0 x 5.5 x 3.5 cm.

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.

Size: 5.0 x 4.4 x 2.5 cm.
Main crystal: 19 x 6 mm.

Large group of cubic fluorite crystals showing well defined faces and edges. The yellow honey color, brilliance and transparency of the crystals give a very aesthetic touch to this piece. Viewed under magnification they are peppered by small globular aggregates of pyrite. It is accompanied by white dolomite.
