At the Fabre Minerals stand you can spend hours and hours viewing the huge number of pieces shown, with each of the details that these offer. It is another thing to choose one from among so much variety, one that fits in the collection, both for one's collection criteria and budget

JFD196AP3: Its form is a luxury. The Quartz crystal is long and has a deep twist enabling us to imagine it as a very showy arch, even more so for being on a kind of natural base, also formed of Quartz. Of all the Alpine finds in the Saint-Jean-de-Maurienne area, this one stands out for its attractive deformity.
Le Noirey, Saint-Jean-de-Maurienne, Savoie, Auvergne-Rhône-Alpes  France (1980)

Specimen size: 11.7 × 7.7 × 4.6 cm = 4.61” × 3.03” × 1.81”

Main crystal size: 11.2 × 2.3 cm = 4.41” × 0.91”

For several years the Expominer Show was held in this pavilion, number 6 of the Montjuïc Fairgrounds. It was later moved to pavilion number 1, much larger and with better accessibility

Among the parallel activities held during the Show are the conferences organized by the Grup Mineralògic Català (GMC) where the academic world approaches that of collectors and the general public attracted by the Earth sciences

Looking is irresistible when faced with so much beauty and mineral variety.

Imagining this creature alive and in its habitat is somewhat scary. Luckily we see it here in fossilized mode.

Ester Pulido and her husband Juan Nicolas Mesas of the company Tesoros Naturales, from Zaragoza, Spain, are regulars at mineral shows and can be considered veterans of both the national and international scenes

Here are two people who modernized the GMC with their drive and tenacity, leading the Grup Mineralògic Català to a level never before achieved: Frederic Varela and Marti Rafel, Chairman and Vice Chairman of the Group during their mandates

The workshops organized by the GMC are a guaranteed success. In this photo Pep Ignacio is explaining the properties of gypsum crystals to a group of schoolchildren. Judging by their expressions on the image, they are really interested. The future for geologists and collectors seems assured

When the Show was held in pavilion number 6, there were really long queues to enter

One of the workshops that never fails to be popular is on the technique of panning to search for gold. And the fact is that gold fever is never far away… and may still be here! Even Spanish public television is interested in the subject, while the kids are waiting impatiently for their next turn at panning to start

Looking, observing, and not touching too much, are essential behaviors in front of a mineral stand

An activity that never fails to attract people of all ages, the opening of geodes... in search of crystallized holes

In a show like Expominer you can find minerals from all over the world. In this case the crocoites from Tasmania, in distant Australia, play a major role

Photos yes, but of the stones. Thank you!

They say children don't lie. Well, seeing the looks on those faces, it is obvious that minerals are attractive and that they often arouse much greater interest than other ‘objects’

Those of us who were lucky enough to know Joan Viñals know what he was like. Those who did not know him should know that the world, including the mineralogical world, is a little better thanks to people like him

Learning in science is based on observation and experimentation, something that that is well developed in children. The future belongs to them

It is never too late to learn or remember the "old" days, with specific lectures on what we like

On an intermediate scale between children and adults, secondary education is of vital importance. Thanks to the GMC (Catalan Mineralogical Group), prizes for research in the geological sciences are awarded, with the collaboration of the sponsors: Kunugi, Fabre Minerals, and Kucera Minerals
