Erongo always offers surprises like this. A very rich group of schorl crystals, with a striated prism and terminal rhombohedral faces, one side very defined, the other fibrous, really curious. They are implanted in a matrix of feldspar, along with green fluorite crystals that give it an interest and excellent aesthetics. THE MAIN CRYSTAL IS: 3,1 x 1,7 x 1,3 cm.
