Rosell Minerales

Group of barite crystals, of good size, well defined and richly faceted, transparent to translucent and with a honeyed hue. They are disposed in a very aerial way on a matrix with fluorite and quartz.

Size: 7.6 x 4 x 3.5 cm.
Main crystal: 2.3 cm.
Found in ±1990.

Group of very good size baryte crystals, well-defined faces and edges, transparent to translucent, with inclusions of pyrolusite and quartz.

Size: 5 x 3.8 x 2.8 cm.
Main crystal: 3.6 cm.
Found in ±1990.

Classic locality

An azurite specimen from this classic German locality, to be enjoyed under magnification. These are aggregates of azurite crystals, some isolated, richly faceted, with transparence, brilliance and the characteristic colour. With globular aggregates of malachite. Very aesthetic.

Size: 4.8 x 4 x 3.8 cm.
Main crystal: 4 mm. agreg.

Classic locality

The silver specimens from this classic German mine has been known for a long time, but in these specimens silver is included in chrysocolla, of an intense greenish blue colour, and shows a remarkable luster, sometimes with golden iridescence. Under magnification we can see facets of crystals of this metal. We have analyzed these samples and the results indicate that they do not contain other metals detectable by SEM-EDS. These specimens are already a few years old.

Size: 6.2 x 4 x 3 cm.

Analyzed specimen with report

Grube Clara baryte specimens are a classic for the species in Europe. In this specimen we can enjoy numerous crystal aggregates, some isolated, presenting a rich complexity of facets. They are mainly formed by faces of orthorhombic prisms and curiously some are translucent while others are totally transparent. The brilliance, transparence and contrast on the matrix add aesthetics to this specimen.

Size: 7 x 4.4 x 2.5 cm.
Main crystal: 7 mm.

Classic locality

From this classic German locality, Grube Clara, we get this specimen formed by aggregates of acicular crystals of sellaite, an unusual magnesium fluoride.

Size: 2.5 x 2.3 x 1.4 cm.
