Classic locality

A very rich specimen of lammerite aggregates, green in color, in several geodes we can observe crystals of this rare copper arsenate. It is accompanied by groups of blue lemanskiite crystals (previously identified as lavendulana).

Size: 7.2 x 4 x 2 cm.

A very good-sized specimen of atacamite formed by numerous radial aggregates of tabular crystals, of intense green colour and transparence, which are disposed on a matrix with chrysocolla and malachite. This specimen has both sides worthy of a display case. It is accompanied by the handwritten label of Joan Viñals.

Size: 7.8 x 6.2 x 4.2 cm.

Classic locality

Rich group of orange lenticular crystals of schwartzembergite, analyzed by SEM-EDS, accompanied by seeligerite, of a light yellow color. Both are rare lead cloroiodates. It is one of the several specimens those remembered Dr. Joan Viñals (1951-2013) brought and studied from his trip to Chile in first years of 2000's. With the E. Kucera (Barcelona) label.

Size: 7.5 x 4.4 x 2.4 cm.
Found in ±2000.

Analyzed specimen with report

Very rich group of sharp chalcocite crystals, some isolated and other interpenetrated, tabular and with very clear twinned pseudohexagonal forms. Intense metallic luster, gray color. They stand out on a matrix of bright calcite and small tennantite crystals. The specimens of this locality are very rare. Novelty in Sainte-Marie-aux-Mines 2017. The Mantos Cobrizos mine is a type of "mantle" deposit. This is a small Cu deposit, located in the mining district of Los Cóndores, close to Paipote, Copiapó. So far the production has been made a small scale.

Size: 7.2 x 6.6 x 3.7 cm.

Sky blue ammeneite occurring as minute crystals on and in halite with green atacamite. From the type locality. This is a fairly rare copper halide and is the first mineral known to contain ammonia radical cation (·NH3) groups.

Size: 3.4 x 2.7 x 2.6 cm.

Molybdenite specimens from Inca del Oro are very difficult to find in the market and more with defined crystals. This sample shows a very well defined, bright and well-disposed hexagonal crystal of molybdenite on the matrix. A unique opportunity to include to your collection a very representative and fine specimen for the species. It belongs from the former J. Astor collection (Barcelona). The locality of Inca del Oro is located between the Chilean provinces of Copiapó and Chañaral.

Size: 7.3 x 4.8 x 3.5 cm.
Main crystal: 1.5 cm.
Found in ca. 1980's.

Rich specimen formed by several groups of linarite prismatic crystals, some isolated and doublye terminated, others forming aesthetic aggregates in rosette. With an intense blue color, very characteristic. They are accompanied by numerous prismatic aggregates of brochantite crystals, of intense green color, together with globular malachite. Very aesthetic and amazing under magnifying glass.

Size: 5.6 x 5.0 x 3.4 cm.

Rich group of prismatic crystals of linarite, which form brilliant rosette aggregates with an intense blue color, very characteristic. They are accompanied by several globular aggregates of malachite, with a light green tone, together with groups of very brilliant, transparent and prismatic crystals of brochantite. Very aesthetic specimen with a good quality for this species.
