RM2561 Boulangerite and pyrite
Noche Buena Mine, Noche Buena, Mazapil, Zacatecas, MexicoA very ancient specimen showing a quartz matrix with carbonates and pyrite crystals. Covered with thin boulangerite needle-like crystals. Very brilliant and dotted with calcite or dolomite colourless rombohedrons. The original handwritten label of the Astor collection, dated in 1978, indicates it comes from Concepción del Oro, but we believe we can say it is from the Mazapil area, a locality very close to Concepción. In those years, geographical themes were not so determined. Adquired in a very "old mineral shop" in Plaça Reial square, Barcelona.
Size: 6.9 x 5.5 x 3.4 cm.
Main crystal: 1.2 cm.
Found in ±1978.

Very defined, brilliant and with a delicate pink tone still visible. These specimens were more pink when collected but over time that hue has faded. Very fluorescent, with yellow and orange tones.

RM2512 Vesubianite
Sierra de Cruces, Municipio de Sierra Mojada, Coahuila, MexicoFloating crystal of vesuvianite, defined faces, doubly terminated, with an intense olive color.

RM2499 Ojuelaite with natropharmacosiderite and arsenopyrite
Ojuela mine, Mapimí, Municipio de Mapimí, Durango, MexicoOjuelaite is a very rare zinc and iron arsenate named after the world famous Ojuela mine (Mexico), its type locality. The species, which belongs to the arthurite group, was accepted by the IMA in 1982 and is isostructural with whitmoreite. It is found in the oxidation zone of the Ojuela deposit, associated with scorodite, adamite and / or smithsonite.
In the article published by Cesbron, Romero and Williams [La mapimite et l'ojuélaïte, deux nouveaux arséniates hydratés de zinc et de fer de la mine Ojuela, Mapimi, Mexique. Bulletin de Minéralogie 104, 582-586. (1981)] two new minerals were described, mapimite and ojuelaite. The studied specimens were obtained thanks to the well-known Mexican mineralogist Don Manuel Romero.
In this specimen, ojuelaite is associated with natropharmacosiderite-pharmacosiderite, as shown by the XRD attached. The arsenopyrite matrix is partially covered by aggregates of natropharmacosiderite-pharmacosiderite crystals, with a green color, brilliant and with cubic shapes. The ojuelaite of this specimen is showing radial fibrous aggregates, with a silky luster and yellow color. We will send the analyzes to the buyer. Former Marcus J. Origlieri collection.
We can say that this specimen is among the best worldwide for this species, due to its size, richness, aesthetics and quality.
Size: 10 x 7.6 x 2.9 cm.
Main crystal: 3 mm rad. aggr.
