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.

Specimens of libethenite from Miguel Vacas mine are seen in the market, but with this size of crystal, brilliance, sharpness and color not really many of them can be find, but rather few. You do not need a magnifying glass to enjoy the pseudo-octahedral crystals of this phosphate. It is accompanied by pseudomalachite, as is usual for the locality, and on a quartz matrix. A first quality one, yes!

Very esthetic specimen formed by some groups of prismatic crystals of adamite, contrasting on a matrix of goethite. The crystals have a very uniform yellow color, with transparency, with very well defined faces and edges and forming rosettes. We can also observe isolated doubly terminated crystals and some almost colorless. A pleasure under the loupe magnifying glass. Good size.

These are brilliant aggregates of gold formed by numerous crystals rich in faces, curved faces and disposed on a matrix of quartz. The SEM-EDS analyzes show that this gold contains a small percentage of silver (<1% weight). They are accompanied by fibrous aggregates of malachite and gray bornite crystals. This specimen stands out for the contrast between the brilliant gold and the green/gray matrix. An exceptional piece. Bleida is a mine located on the eastern rim of the Bou Azzer district.

Glaucophane is an unusual species member of the amphibol group. This Italian locality is known worldwide for the good specimens of this species. It is usually covered with calcite, which once removed shows sculptural aggregates of striated tabular to prismatic translucent crystals, with an intense bluish-gray color, almost violet. In the cavities appear small orange crystals of rutile and groups of chromian muscovite (var. fuchsite). Pyrite crystals also can be found. A good sized and very aesthetic combination from this classic locality.
