Villiaumite is a RARE sodium halide found in alkali massifs and this sharp, lustrous, carmine-red cube of solid villiaumite beautifully accented with white streaks is highly representative of the species and famous locality - Mt. St-Hilaire. The white streaks are tension crack fillings in a very nice pattern. Ex. Carl Davis Collection.
