RM1808   Perovskite with magnetite

Buitrago de Lozoya, Madrid, Spain

Perovskite is an very unusual species, if we add that crystals are in good condition, damage free, and that they were collected in a locality of close to Madrid, the species becomes even more interesting... In this piece highlights a group of perovskite crystals between toasted honey to yellowish tones, cube-shaped, translucent and brilliant. One of them with a good size for the locality. They are accompanied by aggregates of octahedral magnetite crystals. A rarity. Specimen has been repaired consolidating a fissure of the matrix, not afecting crystals.


Size: 6.9 x 3.8 x 2.4 cm.
Main crystal: 3 x 2 mm.

RM948   Fluorcalcioroméite (pseudomorphosis) with baryte

Santa Matilde open pit, Grupo minero Berja, Las Herrerías, Sierra Almagrera, Cuevas del Almanzora, Almería, Andalucía, Spain

At the beginning of 2014, reviewing some specimens from the Santa Matilde open pit we found into the vugs some groups of lanceolated, fibrous or equidimensional crystals, with pink, beige to white colours, those aroused our interest. After some analysis we could identify as fluorcalcioroméite species (Ca,Na)2Sb5+2O6F,OH), with a small percentage of oxyplumboroméite (Pb2Sb2O7, due to the presence of lead). Both species belong to the isometric system. But the observed symmetry indicated that they are, highly probable, a pseudomorph after stibnite crystals. This is the first report of this mineral in the Iberian Peninsula. Nowadays this quarry is completelly filled by rubble. In this specimen we can see some aggregates, one of them predominant, formed by several lanceolated to needle-like crystals, with luster, beige to ocher tone, accompanied by aesthetic baryte crystals. We will send a copy of the analysis (SEM-EDS, XRD) to the buyer.


Size: 6.6 x 4.8 x 4.5 cm.
Main crystal: 4.5 x 3.5 mm.

On a milky quartz matrix we can enjoy some cubic fluorite crystals. One notable for its size. It shows transparency and color zoning. This color zoning is very interesting because it takes the form of an octahedron with an intense violet included in a colorless cube. It is not easy to find samples of fluorite from Cerro Muriano; so even a small dent in a corner, this piece is great quality for the locality.
