Stannite

Preguiça Mine

Descloizite is a mineral not well known in good quality specimens from the European continent. Even considering that the Preguiça Mine, in Portugal, was known for years for its Descloizite and a wide variety of zinc minerals, the quality of the samples was not especially high because the crystals were too small or not esthetic.
Between 2005 and 2006 groups of collectors from Huelva (Spain) were intensely working that mine and finally found some pockets with specimens of Descloizite of high quality, some of them particularly esthetic (and scarce) stalactitic or columnar and associated with white Calcite.
In our opinion these specimens can be considered as the best Descloizites found in Europe.

Just to be certain, we analyzed them and the analysis proved that they are definitely Descloizite. To be more exact, slightly copper rich Descloizite, but the mineral species is Descloizite. We will send a copy of this analysis to our customers who buy this material.

Fluorite

NG49AH2: Polycrystalline growth of Fluorite crystals clearly beveled by the dodecahedron. They are transparent, bright and have a very intense sky-blue color and a central nucleus with a very deep violet color. A picture of this sample has been published in the article “Vale das Gatas Mining District” in Mineral Up magazine (2017/1, pg. 23), and it is from the collection of Pedro Alves, the article’s author, whose samples have been used to illustrate it. We’ll send the collection label to the buyer.
Vinheiros Mine, level 4, Vale das Gatas mining group, Sabrosa, Vila Real District, Norte Region Portugal (08/2011)

Specimen size: 3.6 × 2.9 × 2.2 cm = 1.42” × 1.14” × 0.87”

Minor fluorescence long & short UV

Fluorite with Quartz and Chlorite

NC97AH2: Very sharp Fluorite crystal cubes. They are transparent and colorless but with deeply violet colored areas mainly concentrated on the edges. The Fluorite has grown on a doubly terminated and complete Quartz crystal. A picture of this sample has been published in the article “Vale das Gatas Mining District” in Mineral Up magazine (2017/1, pg. 35), and it is from the collection of Pedro Alves, the article’s author, whose samples have been used to illustrate it. We’ll send the collection label to the buyer.

Fluorite

ND96AH2: A crystal with polycrystalline growths and rich with skeletal and dissolution shapes, translucent, bright, and with a very intense and deep violet color. We note the scarcity of samples from the Codeceira mine. A picture of this sample has been published in the article “Vale das Gatas Mining District” in Mineral Up magazine (2017/1, pg. 21), it is from the collection of Pedro Alves, the article’s author, whose samples have been used to illustrate it.

Specimen size: 2.2 × 2 × 1.6 cm = 0.87” × 0.79” × 0.63”

Doubly terminated Cassiterite

AE47Z1: Complete, untwinned, floater crystals showing the very well defined faces of two prisms and a dipyramid. The sample is from a known but very little disclosed Portuguese locality from which there have been scarce pieces of this quality.
Boticas, Vila Real District, Alto Trás-os-Montes, Norte Region Portugal (1987-2013)

Specimen size: 2.8 × 2.6 × 2.7 cm = 1.10” × 1.02” × 1.06”

Quartz

AA59Y8: Curious tubular Quartz growing with twists and curves whose surface is coated by small white crystals. The sample is from a locality that is very little known on the international collecting circuits.

Pseudomalachite with Quartz

AD6Z1: Botryoidal and microcrystalline growths of this relatively rare phosphate. They have a very deep and uniform color, are brighter than usual and they are on a Quartz matrix.
Miguel Vacas Mine, Pardais and Conceição Parish, Vila Viçosa, Évora District Portugal (±1980)

Twinned Calcite

AM47Z0: Aggregate of twinned and complex Calcite crystals with the clearly dominant scalenohedron. They are transparent, bright and come from a Portuguese locality from which usually are not many samples.
