This is a esthetic and good size hydrozincite specimen, very rich from Ojuela mine. Quite attractive, with little snowy balls formed by several crystals of the mineral have formed in shallow recesses in a contrasting matrix of limonite. Really nice under loupe... Hydrozincite forms in the oxidation zones of zinc deposits as masses or crusts. Excol. Hubin (B).

Vug in the rocky matrix totally covered by numerous tabular crystals of tarbuttite, forming parallel aggregates of green apple color. These tarbuttite crystals from the Skorpion mine can be considered among the best in the world.

Sold

Aesthetic tarbuttite specimen formed by numerous tabular crystals, forming parallel aggregates of green apple color. These tarbuttite crystals from the Skorpion mine can be considered among the best in the world. They are partially covered with tiny crystals of fluorapatite, rich in Zn, but without becoming skorpionite. To my understanding many specimens of this deposit labeled as skorpionite are scholzite and/or fluorapatite rich in Zn. We will send analysis to the buyer. It is accompanied by lanceolate crystals of hemimorphite. Good sized specimen.

A good-sized specimen of this monoclinic amphibole named grunerite, which in its fibrous form is called "amosite". The name has also been used to refer to other members of the group, and form series with cummingtonite. Grunerite is defined as a monoclinic amphibole belong to the magnesium-iron-manganese amphibole subgroup. A worldwide classic from this South African locality.

Sold

Very rich group of anglesite crystals, which show very good transparence, defined faces and edges, formed by first and second order prisms. They are disposed in a cavity of the galena matrix. From a classic Italian locality from where it is not easy to find anglesite specimens of this quality in the market. It comes from the former collection of L. Daunis (Barcelona) with handwriten label.

This is one of the old jasper specimens collected by Mr. L. Daunis on the Montjuïc mountain in Barcelona. A place well known by Catalan mineralogists and geologists for the characteristic variety of mineral species that have been collected during centuries. It is a jasper piece with a slightly polished part that allows to enjoy the nobility of this semi-precious stone, the rest presents the original tone. A classic Barcelona sample and label that should not miss in a quality collection.

Sold

A huge size orthoclase crystal, showing defined prism and pinacoidal faces. It present a small repared edge made many years ago by the owner Sr. L. Daunis, a very perfect work. Crystal is embeded in this porphyry granite-adamellite, part of the potent dykes with large phenocrysts of potassium feldspar (orthoclase) of great perfection. A classic Spanish locality for the species.

A specimen from this classic locality of the world mineralogy totally different from the seen. It is an old piece of a German collection, made up of an array full of green mottramite nodules. One of its faces has been cut allowing to observe the aesthetic aggregates of intense green tone that remember leaves. He analyzed the sample and shows the presence of a certain percentage of As.The results are sent to the buyer. Something very different from Tsumeb ...

Very rich ramsdellite specimen, a rare manganese oxide, formed by several interpenetrated and some isolated groups of well defined crystals. Brilliance is really notable and on matrix. Ramsdellite from this small and defunct mine in a remote corner of Arizona was first found, in the early 1900s. However, the locality was apparently lost for some time and only rediscovered by the father/son team of Roy Jones and Dick Jones in the 1960s. These specimens are from a recent found in 2016.

A huge size and very brilliant druse of prismatic epidote crystals forming fan-shaped forms, with a deep green color. From this classic Catalan locality where nowadays it is forbiden collect specimens.

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 minor tennantite. 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.

A rich cluster of hyaline quartz crytals from the famous Carrara Marble quarries of Italy. The ancients believed that water solidified in the form of hyaline quartz crystals... Viewing this specimen, its purity, transparence, brilliance and perfection, perhaps we can understand their interpretation. Snowy white marble matrix with dolomite crystals. An Italian gemm.

Very rich specimen formed by numerous prismatic crystals of wulfenite, with orange color. They are brilliant and disposed on the matrix. A specimen more than aesthetic historical, fine quality and from a classic Mexican locality.

Group of fluorite crystals with cubic habit, with good transparence that allows to see a marked color zoning. The main one, shows a cavity in which other fluorite crystals have grown. Very curious. It has a fluorite matrix with interpenetrated cubic pyrite crystals. From a classic Spanish locality.
