Drusy crystals of yellow-green (var. cuprian) powellite. Good sized crystals and with rounded faces. Fluoresces bright yellow under SW-UV light. This mine is the Type Locality for szenicsite.

Sold

Very rich druse of pseudomalachite crystals of intense green color, forming defined, translucent prismatic tabular crystals. Specimens of this species in this mine are rare. The piece belonged to the E. Laskowski collection (Tucson, USA), with the seller's label. Very interesting specimen.

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.

Sold

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.

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.

Very rich linarite specimen of this classic Chilean locality. With crystals of good size, defined and transparent, intense color and good size. Analyzed.

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.
