This impressive XL mineral specimen from Goboboseb, Namibia, combines three fascinating minerals on a gray matrix: light green, botryoidal-spherical prehnite crystals, white-transparent calcite cubes, and transparent quartz crystals. The combination of different crystal forms and colors makes this piece a true highlight.
The partially transparent prehnite crystals show a particularly beautiful spherical growth habit, while the cubic calcite crystals provide an attractive contrast. This specimen comes from an old find and impresses with a stately size of 73×64×58 mm.
