Pedro Ansorena, a true institution in the exploitation of one of the most spectacular mineral deposits that can be visited, the Ampliación a Victoria mine, in Navajún, Logroño, Spain, where world-class pyrites are found. It is rare to find any public or private collection that does not have a Navajún pyrite on display

The Revista de Minerales / Mineral Up stand with Joaquim Callén doing -how could it be otherwise?-photography, and his wife Eloïsa Artola (RIP) putting everything in its right place

Meeting of the illustrious: Inma Ramos, Martí Rafel, Biel Fiol and Antono Carmona. Good cast of enthusiastic mineralogists coming from different cardinal points of the Iberian peninsula.

A photo that sums up very well what a mineral show is. See, observe and as far as possible understand... even purchase a specimen!
