RM2197   Pyromorphite with coronadite and quartz

Bedures Hill, Meredo, Vegadeo, Asturias, Spain

As M. Calvo indicates in his work (Minas y mInerales de España), in the area of Bedures hill (or Vidures), in the municipality of Vegadeo, there are several mining works, some of them very ancient, in which various lead mineral species have been described and among them, pyromorphite stands out. This piece we propose, found by chance in a mineral show far from the mine that saw it born, shows a matrix of milky quartz, with iron oxides and a black layer of coronadite in one side. We can observe also several crystals of green pyromorphite on the surface. Some form divergent aggregates, others isolated, but with an intense green color, with zoning in some of them. They show hexagonal prisms truncated by pinacoidal faces and parallel growth aggregates. A very rare specimen for this Spanish locality.

RM2196   Pyromorphite with coronadite and quartz

Calvo indicates in his work (Minas y mInerales de España), in the area of Bedures hill (or Vidures), in the municipality of Vegadeo, there are several mining works, some of them very ancient, in which various lead mineral species have been described and among them, pyromorphite stands out. This piece we propose, found by chance in a mineral show far from the mine that saw it born, shows a matrix of milky quartz, with iron oxides and, on it, a black layer of coronadite. We can observe also several crystals of green pyromorphite dot its surface. Some form divergent aggregates, others isolated, but with an intense green color, with zoning in some of them. They show hexagonal prisms truncated by pinacoidal faces and parallel growth aggregates. A high quality and very rare specimen for the locality.

RM2189   Epidote and quartz

Los Serranos quarry, Fondó dels Frares, Albatera, Alacant, Valencia, Spain

Very aesthetic group of deep green epidote fan-shaped aggregates on matrix. Epidotes have a good luster and intense green colour. There are some gemmy quartz crystals emerging from the epidote. The original label we will send to the buyer indicates that those crystals are clinozoisite, but recent studies show that all the analyzed specimens are epidote (Calvo, M., Subías, I. (2017): Epidote (not clinozoisite) and andradite garnet from Los Serranos quarry, Cabezo Negro, Albatera, Alicante. Mineral Up, 4:44-47).

This specimen is from the famous Rosenberg mine, in Bad Ems, Germany, closed since 1963. It is accompanied by a typed label by Juan Montal, a well-known Catalan mineral dealer from Vilafranca del Penedés (Barcelona), who was active in the middle of the s. XX until the 1980s. The piece is very good for the locality and the label full of history. An European classic.

RM2185   Aragonite

La Pesquera, Cuenca, Castilla-La Mancha, Spain

Many specimens of aragonite are seen, as "pinecone" shape, also isolated, but this specimen has an "I don't know what" that makes it different for me. An elliptical "pinecone" of prismatic, divergent aragonite crystals, which are grouped around a central axis, with more developed crystals. Different and very aesthetic. A classic from Spanish mineralogy.

RM2183   Hydromagnesite

Àngel quarry, Montseny massif, Gualba, Barcelona, Catalunya, Spain

Hydromagnesite specimens from "Pedreres de l'Àngel" (Angel quarries), in Gualba (Barcelona), are a classic for the Catalan mineralogy. In this specimen we can observe some aggregates formed by radiated crystals, some of them of good size (more than 2 cm.), others smaller (up to 8 mm), very brilliant. Nowadays impossible to be found... This mines are a skarn due to contact metamorphism of Hercynian granodiorite and biotite granite into Cambrian marbles.

RM2178   Covellite and sulphur

Corta Atalaya, Minas de Riotinto, Huelva, Andalucía, Spain

This good sized specimen from the late 80s belongs from the Arguijo collection, and it was mined in this famous "onubense" mine. It is a sulphide matrix partially covered by brilliant covellite microcrystals, very defined and visible. It has an intense metallic blue iridescence and this very characteristic color. It is accompanied by numerous crystals of native sulphur with curved faces, brilliance, translucent and showing a delicate yellow tone. It was mined from a sporadic finding in the Corta Atalaya, Minas de Riotinto. A unique occasion to obtain one of these "old" specimens.

RM2194   Scapolite (Meionite), magnetite, epidote and actinolite

Burguillos del Cerro, Badajoz, Extremadura, Spain

Aggregates of prismatic crystals of meionite, with cross-linked and parallel growths. It is arranged in a matrix with octahedral magnetite crystals, green epidote and actinolite fibers.
