Excellent specimen, with a good size, of granatite with vugs filled by epidote crystals, on which olive green fibrous aggregates of uralite stand out. The most remarkable are several well-formed crystals of scheelite, a species difficult to find locally, highly fluorescent under short-wave UV. It belongs from the Manchion collection and it was acquired from Joan Viñals in 1990.

Classic locality

Very good size specimen formed by laminar aggregates of stibnite crystals. The San Antonio mine is located in the area called "Quinola" next to the road BA-5001 between the peoples of Alburquerque and The Codosera. This is an important antimony mine closed in 1986, and it was the largest mine of this metal in Spain and Europe. It belongs from the former Arguijo collection and dates from the 90s.

Classic locality

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. Joan Viñals indicated on the label of this specimen (we will send to the buyer) meionite, although specimens such as marialite are described in the area. The marialite-meionite series refers to the proportion of Na and Ca, both of the escapolite group. "Probably from the La Herrería mine where it usually appears in magnetite vugs as acicular and radial aggregates of tetragonal prisms, sometimes centimetric, whitish to transparent" (Mti-Blog).

Group of sharp andradite-grossular crystals, with an exceptional brilliance and a brown color, near to black. They show clear faces of the dodecahedron and the trapezohedron. Disposed on the matrix, contrasting with the white albite and small octahedral crystals of magnetite. A sample of the former Daunis collection; from a Spanish locality not well represented in collections.

Analyzed specimen with report

From a recent finding in an outcrop close to the Proserpina reservoir, near of the interesting city of Mérida (Badajoz). This specimen shows small turquoise crystals forming botryoidal aggregates with a nice bluish and greenish tones, partially covered by a second generation of more yellowish crystals. We'll send a copy of the analysis to the buyer.

This specimen shows a very rich group of small micaceous crystals of tyuyamunite, brilliant and intense yellow color, contrasting on the matrix. The piece was labeled as francevillite, but we have performed SEM-EDS analysis that refers to the tyuyamunite species. The results indicated the presence of uranium, calcium, vanadium, and few silicium, thus move away from the francevillite containing barium and lead, together with vanadium and uranium. Results will be send to the buyer. From a Spanish mine not well represented in collections.

A very rich group of prismatic crystals of ferro-actinolite of intense green, near to black color, brilliant, defined, with flattened terminal faces and some with pyrite on them. Aesthetics is excellent and the vertical disposition of the crystals makes this piece a different sample.
They are disposed on a matrix of albite with several rounded and brilliant magnetite crystals. Also with small pyrite with complex and interesting forms. This specimen is an excellent representative for the species and more, if possible, for this Spanish locality.

A miniature formed by a druse of translucent and brilliant hexagonal barrel-shaped pyromorphite crystals. Some of them show parallel growths. With a color zoning that varies between grass green in the center to beige-green on terminal pinacoidal faces. These specimens have been determined by isotopic studies with equal results to those of this mine. This sample is from an old German mineral collection.
