Another superb piece from the Hauck Collection, this is a very unusual POKER-CHIP form smithsonite from Berg Aukus! These pearly, flat crystals are selectively coated with a deep olive-gray mineral on the display side, which gives them their color. The crystals are quite large - to 1.5 cm across! A remarkable specimen, and something you just do NOT see on the market! 6.3 x 4.8 x 3.4cm
