Since childhood, minerals have been an incentive for me, a source of inspiration and to some extent a refuge where I feel happy. With the passage of time that love and admiration for minerals has not stopped growing, to the point of devoting my holidays to visiting the most important mineral shows in Europe, such as Sainte-Marie-aux-Mines and Munich, and thanks to this I have been fortunate to meet some very diverse people.

One of them is Jordi Fabre, who has spent a lifetime dedicated to the mineral trade and little by little has gathered a large number of specimens that he has never been able to put up for sale due to overaccumulation of work. Being well acquainted with the situation and these specimens, I spoke with Jordi and we concluded that since he had no time to take care of what was once "Express Minerals", there was no section on his website dedicated specifically to pieces that deserved to "come to light" but that at the same time had affordable prices.

Because of all this we agreed that a series of economic pieces from Fabre Minerals‘ reserves will be offered here with the desire to reach all those interested in mineralogy and especially the younger collectors. This page will function completely autonomously, It will be managed only by myself, and will be updated as continuously as possible but without fixed dates for updates, so I recommend visiting often to see what has been added.

I hope the specimens offered are to your liking, as selected from my particular point of view, with reasonable prices and with the seal of approval of Fabre Minerals.

Very Important: For all correspondence related to specimens on this page, please contact my mail: [email protected] and not Jordi.

Silver (variety kongsbergite)
 

21PRX61: In the classic Las Herrerías Mine, works done in 1999 has revealed new Silvers in the zone of secondary enrichment, quite similar to those found many years ago in that mine and which are represented in the world's most important museums. The new pieces have a very high content (±10%) of Mercury. In addition, when analyzing them, we saw that they had a large amount of Chlorargyrite scattered throughout. As always, we will send a copy of these analyses to whoever buys the piece. This particular specimen is very solid, unlike the more 'fluffy' classical pieces, and exhibits very aerial growths.

Mimetite, Galena, Baryte
 

21NBX11: An important find from the well-known Atrevida mine in the summer of 2015 uncovered a single pocket, with coatings of greenish yellow millimeter-size Mimetite crystals, very sharp, translucent, and formed by an elongated prism and acute dipyramid.

The Sphalerite crystals are associated with groups of very shiny octahedral and cubo-octahedral Pyrite crystals with polycrystalline growths on their faces. The culmination is several rosettes of Calcite crystals colored grey by Boulangerite inclusions.
The Trepča mining complex is one of the largest polymetallic deposits in the world and for many years produced exceptional specimens of Sphalerite as well as various combinations of sulphides and carbonates, as shown in this specimen from the former collection of Ferat Voca.

New Oldies

After more than 23 years offering minerals on the Fabre Minerals website some of them have been somewhat forgotten after so many updates. That is why, starting with this section, we intend to rescue some specimens, with an improved image, an updated descriptive text, and at a very competitive price. These "oldies" in the Internet age deserve a review and perhaps even to become part of our collections.

9MC14F5: One can see different crystals that have grown in various directions. To me it looks like it is the very complex crystallization that gives the specimen so many faces, which means that any movement creates numerous reflections. It is a very original floater with zones of smoky color and multi-colored reflection from its interior. For Quartz specialists.

Lazulite, Siderite, Quartz
 

10MF13: Aggregate of very sharp Lazulite crystals, twinned, very shiny, with an intense luster and a deep blue color, on matrix with translucent light brown rhombohedral Siderite crystals, and small water-clear Quartz crystals. Lazulite is a rare magnesium aluminum phosphate. Some of the best known examples of this species have been found in this remote area, accessible only during the summer months as they are under snow and ice the rest of the year.

Prehnite

Recorded under neon light
 

17NRM16: Fan-shaped aggregates of bright, light green Prehnite crystals forming globular groups implanted on an ophitic rock matrix. From a classic Spanish mineral deposit very close to the well-known sulphur mines of Conil de la Frontera, in Cádiz, where ophitic bodies outcrop between Triassic sedimentary rocks, specifically in the Keuper facies. A specimen difficult to find nowadays on the commercial mineral circuit.

7NC40: Minas de El Horcajo will forever be associated with legendary Pyromorphites. Hearing or reading this name transports us to a mineralogical myth, often a source of desire. At the beginning of the 20th century, the El Horcajo mine produced excellent specimens of Pyromorphites of various shapes and colors. It is exciting to be able to offer a number of this type of pieces past more than 100 years, a true oldie.

Miniature formed by prismatic crystals, of excellent color, some of them doubly terminated and with color zoning.

Brucite, Dypingite
Brucite, Dypingite.
 

18NK46: Botryoidal aggregate of Brucite, with small traces of matrix and visible crystal forms, which is unusual for the species. Apart from the excellent luster, the unusual quality and intensity of the uniform lemon-yellow color stands out. Partially covered by transparent whitish crystals of Dypingite. Geologically, both species are found in peridotites as the product of serpentinization in a regional ophiolite complex.
The Dypingite and the Brucite has been analyzed and we will send a copy of the analysis to the buyer.
