This specimen shows a rich group of lanceolated austinite crystals with an excellent transparence and brilliance and a slight greenish tone. They contrast on the goethite matrix layered by several sharp adamite crystals, defined, brilliant and with a yellow to orange color. A sample with aesthetic and mineralogical interest for the quality of the austinite and its paragenesis.

In this double specimen we did not want to separate the two parts because symmetry gives them a very nice aesthetic touch. We can observe nodular aggregates of variscite. The green color is very intense. They are embedded in a type of silicified breccia matrix with iron oxides. Both are polished in the front side (which allows us enjoy the structures) and natural cut in the back side. To find samples of this quality you must go back to the past times.

In this double specimen we did not want to separate the two parts because symmetry gives them a very nice aesthetic touch. We can observe nodular aggregates and possible tigmatic folds in the veins of variscite. These meandering folds are caused by the flow of a viscous fluid into a more fluid media. The green color is very intense and it is combined with whitish and yellowish areas. They are embedded in a type of silicified breccia matrix. Polished in the front side (which allows us enjoy the structures) and natural cut in the back side. To find samples of this quality you must go back to the past times.

Curious globular aggregates formed by numerous fluorite octahedral crystals that have grown together, reaching this globular shape. If you look closely under magnification the specimen you can observe different growing phases. So we can see perfect small colorless octahedra, others as groups of a few crystals sharing faces and symmetry, and some with many octahedrons close to this globular shape. Very fluorescent under SW-UV.
This green color is the best ever found for this site, with transparence and brilliance. They are disposed on an matrix of hard porphyry covered by minute quartz crystals, with calcite and goethitized cubic pyrite.

This area is known as Singuerlín (a neighborhood of Santa Coloma de Gramenet city, close to Barcelona) and from 60's collectors has found these globular aggregates with tones between white, yellow or slightly greenish. Then some specimens were analyzed and labeled as gearksutite. More recent analysis did not indicate the presence of this species but only fluorite.

Group of very sharp fluorite crystals which show good transparency and lilac to purple color. They are disposed on a matrix with feldspar and smoky quartz, accompanied by small prismatic crystals of brilliant prismatic stilbite, transparent and vivid orange color. Also with groups of clinochlore crystals, with dark brown to nearly black color.
This specimen was collected from miarolitic pegmatites veins in granite of the Strzegorn-Sobótka massif quarries. These quarries are worked for aggregates and miarolitic cavities are scarce. These specimens are coveted by collectors, mainly German and Poles, unusual in other collections.

Nice specimen from the former mineral collection of Henri-Léon Ungemach (1879-1936). The sample corresponds to the label. Sometimes is difficult this relation, or specimen has no number on or number do not match.

The cavity is covered by scalenohedral calcite crystals, and on them groups of brilliant galena and pyrite. We can observe some idiomorphic crystals, with defined faces and dull luster, of stephanite. A sample with its own history.

Unusually species for this Moroccan mine. The dealer confirmed the locality, I initially thought in Imiter. This is a group proustite crystals with good red color, brilliance and transparence, some of them contacted due to the cavity, others showing terminations and striated faces. In calcite matrix.

A huge size specimen of malachite that has completely replaced azurite former crystals, preserving its prismatic shape, with visible terminal faces. Malachite has an intense green color, with silky luster due to its acicular shape, fibrous. With a minor rocky matrix. An elegant specimen of a classic mine as Touissit.

Let me add another "delicious" specimen of kutnohorita with manganoan calcite. Kutnohorite is a rare member of dolomite group, a calcium carbonate with manganese, magnesium and few iron... uncommon. In the specimen appears as acicular snowy white crystals on which have grown a large group of pink crystals of calcite with manganese. Good brilliance and calcite extremely fluorescent with reddish tone. In the back side we can observe a particular radial aggregates of kutnohorite, this is another shape of the species. We have both in the same sample... The aesthetics of the formations is unquestionable and the species is a classic hard to find.

This huge size specimen combines two very interesting species. On one hand we have spherical aggregates formed by radiated polysynthetic growth of poldervaartite, showing slightly curved top faces, with a very uniform beige and good luster. We would like to inform you that these specimens were found in the mine in late 2010 and were collected very few specimens. They were analyzed by SEM-EDS, and it was found that the external and surface crystals were mainly determinated as poldervaartite, while the inner concentric growths presents poldervaartite and olmiite mixture. This makes us confirm poldervaartite in this mine.
Only for this species this sample is excellent. But it is accompanied by xonotlite, an uncommon calcium silicate, in the form of fine needles, brilliance and flexible. A stunning combination. To increase its interest we can say that this sample is one of the few of this vug, from this popular South African mine. A great opportunity. We will send the analysis to the buyer.
