4 March (starting at 3:00 PM) - 6 March 2016

Mineralexpo Barcelona-Sants is an annual mineral show that is held during the first weekend of March in the Cocheras de Sants, Barcelona (Calle de Sants, 79). This show, in some senses, takes the place of the Sant Celoni Show as the Sant Celoni show was held during the same weekend, although it is now held during the first Sunday of May.

The people that organize the show are the Grupo Mineralógico Catalán, a group whose objective is to promote mineralogy. So that is why the show has a limited number of dealers, with the aim of focusing on minerals for collectors.
