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 clear quartz crystals. The partially transparent prehnite formations create a beautiful contrast to the geometric calcite cubes and the gleaming quartz. This specimen comes from an old find and captivates with its exceptional combination and size. A true highlight for discerning collectors!
