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.

Calcite
Calcite. Calcite.
 

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. A very decorative piece originating in the Cretaceous carbonate strata of the Sierra de Santa Eulalia.

Diopside, Vesuvianite
Diopside, Vesuvianite. Diopside, Vesuvianite.
 

5MC51J7: The habit of these crystals of Diopside is uncommon: although apparently tabular, the fine vertical striations and the presence of the pinacoid show that they are, in fact, very flat prisms. Their color and luster are excellent, and they are implanted on a group of prismatic crystals of greenish yellow Vesuvianite with intense violet terminations. The Jeffrey mine has been closed since 2001, so it is very difficult to find this type of specimen from this locality.
