This impressive XL mineral specimen from Goboboseb, Namibia, combines three fascinating minerals on a grey matrix: light green, botryoidal prehnite crystals, white-transparent calcite cubes, and transparent quartz crystals. The combination of different crystal forms and colors makes this piece a real eye-catcher.
The partially transparent prehnite crystals show a particularly beautiful botryoidal growth habit. This rare specimen comes from an old find and impresses with its size and quality.
