Fascinating mineral specimen from Goboboseb, Namibia, with an impressive combination of light green prehnite spheres, white calcite cubes, and transparent quartz crystals on a gray matrix. The prehnite crystals show conchoidal to spherical growth and are partly transparent, while the calcite cubes and quartz crystals shine in white-transparent quality. This specimen comes from an old find and is a true collector's item for lovers of combined mineralizations.
