SV3390EXL: A great piece from the San Valentín Quarry. The Quartz crystals are of good size, the Goethite that covers them has intense iridescence and the whole thing has a strange beauty. There is a slight saw cut on the back that barely impacts the visual appearance of the specimen.
This piece was in one of the great collections of that area, that of Mariano Guillén. His collection passed to that of Miguel David Martínez with the number 1700 and whose label we will send to the buyer of the specimen.
