Minrecordite is an anhydrous carbonate mineral with the chemical formula CaZn(CO3)2. It forms transparent to translucent crystals that typically display a pearly lustre and a light, colorless to white appearance. The mineral crystallizes in the trigonal system and shows a Mohs hardness near 4, with a relatively high specific gravity for carbonate minerals and a perfect cleavage along its crystallographic planes. These features give Minrecordite a distinctive, clean look when well-formed crystals are encountered in collections or mineral cabinets.

About Minrecordite
Most celebrated examples come from Namibia, where geologic conditions have produced well-formed specimens that attract collectors for their purity and the locality association. The combination of its pale hue, glossy surface, and clear terminations makes Minrecordite appealing for display and study, particularly when sharp crystal faces and intact crystal forms are present. As a carbonate mineral with zinc and calcium, it sits among the rarer carbonate species and offers a compact, attractive option for modern cabinets seeking both colorless elegance and scientific interest.
