[Jordi Fabre]

Hexagonal floater crystal of Laurentthomasite with very marked polycrystalline growths, transparent and with an intense deep blue color. The species, a magnesium-potassium cyclosilicate, is a rarity recently (2019) approved by the IMA. From the type locality for the species.

[Jordi Fabre]

Multiple growth of dipyramidal crystals with sharp faces and edges, on matrix with leafy aggregates of Muscovite crystals. Large size of both the piece as a whole and the Scheelite crystals, which at the time were a relatively abundant species and which today have become difficult to obtain.

[Jordi Fabre]

Two cubic Fluorite crystals beveled by the rhombododecahedron and with geometric color zoning.

[Jordi Fabre]

Druse of complex Calcite crystals with dominant scalenohedron faces and with reddish inclusions of Hematite. An English classic, really old and with a complex pedigree, with two labels that detail much of its history. It came from the collection of Francis Butler, who in 1890 sold it to the British Museum in London, which gave it the collection number BM65723, after which it passed on to the Leif Engman collection.

[Jordi Fabre]

Proustite crystals with very well defined faces and edges and pyramidal terminations, transparents and with small white Quartz coatings.

[Jordi Fabre]

Complex Sphalerite crystals with curved faces and edges. On matrix with white rhombohedral Dolomite crystals.

[Jordi Fabre]

Aggregate of elongated octahedral crystals with skeletal and hollow growths but with well defined crystalline forms.

[Jordi Fabre]

Group of crystals of cubic habit beveled by the rhombododecahedron, translucent and on matrix with small Quartz crystals.

[Jordi Fabre]

Rosette growths of lamellar Wurtzite crystals with a very sharp hexagonal contour and unusually large in size for the species, on matrix and with cube-octahedral crystals of Galena. This well-known specimen, which comes from the Rock Currier collection (No. 6516), is considered the best of the find and among the most reputable.

The upper levels of the great classic mine of Panasqueira are now producing very good specimens. We have gone from a period of scarcity to the current wealth, but in my opinion we are in a transitory period that may end when the mine goes to different areas. So far several pieces as this zoned crystal of Fluorapatite, isolated and well placed on its matrix of Quartz and Muscovite, have been recovered.

[Jordi Fabre]

Very aerial group of Quartz crystals twinned by the Japan-law and doubly terminated. The crystals have inclusions and negative forms of Quartz inside.

[Jordi Fabre]

Group of almost colorless crystals of Fluorite, with the transparency that characterizes the finest specimens from the Emilio Mine. With scalenohedral white Calcite crystals and small Dolomite crystals.

[Jordi Fabre]

Sharp Fluorite crystals with a uniform violet color, more intense on the edges. On a matrix of Quartz crystals partially covered with small white Dolomite crystals.
The specimen comes from the #Jan_Buma collection (number 040704)

[Jordi Fabre]

Crystals of Vanadinite on a white Baryte matrix, some with very marked hopper growths. A specimen that comes from the collection of Josep Amigó (Silvane)
