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.

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.

The sample is from material compiled for years by Fernando Brugos, former owner of the La Viesca claim. This material has been accurately documented, regarding the different pockets as well as the dates of the finds. A classic, currently very difficult to find.

8TY16V4: A novelty at Tucson 2012. Unusual crystalline shape for the Vanadinite, whose aggregates, very aerial, are formed by crystals with a prism and an acute dipyramid with very well defined faces and edges and are on matrix with small crystals of Calcite. They show a creamy color and are on matrix.
This sample has been noted and photographed in the Mineralogical Record magazine (January-February 2018, pg. 167)

5FT86: Two generations of Calcite. The first generation is stalactitic Calcite, while in the second generation the Calcite takes the more classic crystalline form for the locality. Crystals of both generations have good luster, and both appear partially colored by brown iron oxides.

Diaspore
 

18EZZ26: Diaspore is an aluminum oxy-hydroxide that rarely develops into crystals. Fortunately, in Turkey there is a classic deposit where the crystals show good development, color and transparency, as is the case of this specimen, terminated and with a light yellowish-greenish color and with fine vertical striations. This mineral, together with Boehmite and Gibbsite, make up bauxite, a rock which is the main ore of aluminum.

Brucite, Dypingite
 

18NT76: Botryoidal aggregates, with visible crystal forms, something not very common for the species, and with remnants of matrix. 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
