Group of interpenetrating fluorite crystals, with an intense coluor that varies according to the type of incident light. From this classic Asturian mining area.

Size: 6.1 x 4 x 3.5 cm.

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

Specimen formed by aggregates of radial aragonite crystals, with very aesthetic bands of delicate blue color. This old specimen (1980s) is labeled as collected in Peñamellera, Asturies (Spain). Other specimens like this and from the same years where labelled as collected in this Asturian locality. A curiosity from the former Joan Astor collection (Barcelona). With original labelled box.

Size: 6 x 5.5 x 4.7 cm.
Found in ±1985.

Fluorescent under long wave UV

Tetrahedrite crystals from this Asturian mine are well known and prized by Spanish collectors. In this sample we have tetrahedral crystals, one of them predominant, in which the tris-tetrahedron shapes seem to point. Good size and partially covered by malachite. X ray diffraction analysis (we will send to the buyer) has shown the presence of digenite associated with the alteration of the tetrahedrite. A classic.

Size: 3.1 x 2.7 x 2.5 cm.
Main crystal: 1 cm.

Analyzed specimen with report

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.

They show hexagonal prisms truncated by pinacoidal faces and parallel growth aggregates. A high quality and very rare specimen for the locality.

Stalactitic to botryoidal aggregates of smithsonite of yellowish tone, partially covered by a second generation of the same species, colorless to white. This mine is located in the Magdalena concession, near Robriguero, with gallery and open pit works. The mine was worked until 1924 to obtain calamine and some galena. Nowadays it is very difficult to find samples.

Size: 6.2 x 6 x 5.2 cm.
