Near the coast of the Catalan city of Barcelona is emplaced this historical and geologically very interesting promontory such as the Montjuïc mountain. The sample we propose is a xylopal (opal wood) in which we can observe structures of the original wood. These specimens are already as historic as the mountain from which they belong...

This is one of the old jasper specimens collected by Mr. L. Daunis on the Montjuïc mountain in Barcelona. A place well known by Catalan mineralogists and geologists for the characteristic variety of mineral species that have been collected during centuries. It is a jasper piece with a slightly polished part that allows to enjoy the nobility of this semi-precious stone, the rest presents the original tone. A classic Barcelona sample and label that should not miss in a quality collection.
