Silver
	NF59H1: The growth is laminar which is uncommon in the samples from Falset. Another aspect to distinguish the specimen is that it hasn’t been etched out with acid because the Silver is found in fissures and is not included in Calcite.

In a small quarry near Barcelona, appeared good samples of smoky Quartz and exceptionally some Quartz Amethyst. Lots of local collectors go there on the weekends hoping to find the sample of their dreams. As we know many of them we hear about new finds and see the specimens found. Here are some of them. If you want to know more about Sils Quartz please follow this link

	Quartz (Amethyst)
NB57F0: The most notable thing about these crystals is the way the rhombohedral faces of the termination are much larger than the prism faces. The color is intense and the coloring is not evenly distributed within the crystals. The rear has re-crystallized. Massabé Quarry, Sils, La Selva, Girona  Spain (2004) Specimen size: 4.5 × 3.5 × 1.5 cm

	Crandallite after Fluellite
NG13E8: A mineralogical rarity. The Crandallite has been totally substituted by the Fluellite.

Their upper and side faces have very well marked triangular growth figures that give the edges a sawtooth appearance. Also we can see corrosion and contact geometric structures on some faces. We call your attention to the interesting Chalcopyrite crystal inclusions, where the original yellow greenish color is preserved, while superficial crystals on Barite faces are covered by a thin oxidation layer. The specimen is from mining works of Aizpea, close to the La Troya Mine. Minas de Aizpea, Zerain, Gipuzkoa  Spain (03/2001) Specimen size: 6.9 × 4.6 × 1.5 cm Main crystal size: 6.9 × 2.5 cm	Front Rear

	Sphalerite with Dolomite
VB58G8: Being known from the Moscona Mine, Sphalerite is a species rarely found there. On the piece crystals have an uncommon development (for the mine) for their larger size and bright luster. The dark color contrasts with the snowy white of the Dolomite in classic saddle-shaped crystals. Mina Moscona, Solís, Corvera, Asturias  Spain Specimen size: 3.4 × 2.3 × 2.6 cm

Doubly terminated Quartz with Calcite
Front Side	TD16H8: The crystal is doubly terminated and has the short prism typical of the locality. It is transparent and bright and has attractive inclusions of hydrocarbons and the beginning of “windows” on some of its terminal faces. We call attention on the position of the crystal on the matrix that enhances the esthetics of the specimen as well as increases its value because specimens of Quartz with matrix are pretty unusual in Berbes. Berbes, Ribadesella, Asturias  Spain (±1997) Specimen size: 5.3 × 3.9 × 4 cm Main crystal size: 4.8 × 3.9 cm

	Doubly terminated Quartz

Berbes, Ribadesella, Asturias  Spain Specimen size: 7.6 × 6.4 × 4.8 cm Main crystal size: 1.3 × 1 cm

Turquoise (crystallized) with Wavellite
	N6AI0: The locality is well known for Variscite but occasionally some samples of Turquoise had been found there. On the specimen are two microcrystalline concretions of Turquoise on a Wavellite matrix of acicular crystals forming radial greenish yellow aggregates. We’ll provide a copy of the analysis to the buyer. Palazuelo de las Cuevas, Zamora  Spain (1993) Specimen size: 4.9 × 2.4 × 3.8 cm

	Turquoise with Wavellite
NA57L2: The phosphate deposit of Palazuelo de las Cuevas (Zamora, Spain) is well known for the presence of Variscite. This mineral was mined by Prehistoric man. Variscite occasionally is accompanied by Turquoise, Wavellite and other phosphates. In this specimen the coating of Turquoise, as small globular and leafy microcrystal blue greenish aggregates, contrasts with the botryoidal Wavellite. We’ll provide a copy of the analysis to the buyer. Palazuelo de la Cuevas, Zamora  Spain (1993) Specimen size: 4 × 3.7 × 2 cm

Opal
	N58FRH5: Nodular growth with very bright surfaces having an esthetic combination of mainly red shades with yellow and pink. The locality is not so known, so we think these Opals are on sale for the first time. La Tuda, Zamora  Spain (1995) Specimen size: 5.7 × 4.2 × 4.5 cm

	Beryl (Emerald) with Muscovite
L58RL6: A large Beryl (var. Emerald) with intense color. The specimen preserves the hexagonal shape, with curved faces partially covered by Muscovite as a matrix. From the most classic Spanish locality for Emerald, although nowadays it is quite impossible to obtain specimens there. A Franqueira, A Cañiza, Pontevedra  Spain (±1990) Specimen size: 6 × 3.8 × 3.3 cm

Eugui Dolomite

The Eugui quarry in Navarra is famous for its specimens of twinned, transparent or translucent Dolomite. While the quarry is still active, specimens are only found from time to time. In 1997 to 1998 a significant number were found and over the last few years a few more have appeared.

Twinned Dolomite

	Chalcopyrite with Dolomite
BC58C7: When we have visited Eugui over the last few years we have from time to time noted the Chalcopyrites that have been altered to Malachite, associated with the dolomite. Recently the local collectors have found more of these malachite coated chalcopyrites. This specimen shows that these are actually not that new. Cantera Azkarate, Eugui, Navarra  Spain (1980) Specimen size: 5 × 4.2 × 3 cm

Chalcopyrite with Malachite on Dolomite

Sphalerite with Siderite
	N13AHL6: Sphalerite crystals with well defined faces and edges, some of them with curvatures, with good honey color. Most are peppered by small Pyrite crystals. On a matrix with Siderite and Pyrite crystals. This mine closed a long time ago, and it is now flooded and collapsed, so it is quite impossible to obtain specimens there. Mina Troya, Mutiloa, Gipuzkoa  Spain (±1990) Specimen size: 5.2 × 4.2 × 3.1 cm Main crystal size: 1.3 × 0.8 cm

	Sphalerite with Dolomite
N66BI0: An excellent sample, very esthetic, with complex crystals of Sphalerite of very good luster and dark honey color, partially covered by white crystals of Dolomite with so-called saddle-shaped form. The mine was closed some years ago and good specimens are scarce and very difficult to obtain. Mina Troya, Mutiloa, Gipuzkoa  Spain (1990) Specimen size: 7.2 × 6.5 × 4.2 cm Main crystal size: 0.8 × 0.6 cm

Sphalerite
	N11BL6: Group of Sphalerite crystals with well defined faces and edges, some of them with curvatures, on a white Barite matrix formed by tabular crystals, some of them with a good size. An uncommon mineral association for this mine, that closed long time ago. It is flooded and collapsed, and so it is quite impossible to obtain specimens there. Mina Troya, Mutiloa, Gipuzkoa  Spain (±1990) Specimen size: 5.3 × 4.5 × 2.1 cm Main crystal size: 1 × 0.7 cm

On a vug coated by small Quartz crystals which are covered by an orange and black layer; and with Limonite that enhances the Aurichalcite contrast. New find from a quarry of the historical Troya Mine, currently it is flooded and collapsed. Cantera Mina Troya, Mutiloa, Gipuzkoa  Spain (01/2008) Specimen size: 3.3 × 2.3 × 1.4 cm Main crystal size: 0.6 × 0.6 cm

Twinned Pyrite

Spain is a country that is well known for its cubic Pyrite specimens. Although the most famous ones are those found at Navajun the whole region is full of small localities where one can also find crystals of Pyrite. As a result of patient work by a local collector we are able to offer these twinned Pyrites from Valdeperillo. The crystals are well defined and the twinning is solid and stable as no ‘consolidation’ methods were used to try to stop the crystals from separating (they were not required for these Pyrites)

	Twinned Pyrite
NA7E1: Good form and esthetic Valdeperillo, La Rioja  Spain (±1994) Specimen size: 2.5 × 2.1 × 1.8 cm

Pyrite
	ND9K7: Group formed by pentagonododecahedron (pyritohedral) crystals modified by cube faces, with very sharp and brilliant faces and edges. Noting the discovery year and the excellent preservation we believe that they will not be altered in the future. Mina Ambasaguas 1, Ambasaguas, La Rioja  Spain (1994) Specimen size: 3.7 × 3.2 × 3.6 cm Main crystal size: 1.2 × 1.1 cm

	Pyrite
L14DAI0: The crystals have one of the more classical combinations of forms from Ambasaguas, the cube and the pyritohedron, the first delicately striated. But it is not so common to find them on marly matrix because they are easily detached in mining.
