This incredibly attractive and geometric piece displays both cubic crystals and elongate octahedral crystals for a mesmerizing pattern! Guanajuato is one of the world's largest Carbonate Replacement Deposits and Acanthite is one of the main silver ore minerals there. This elegant piece has an elongate triangular shape and is composed of a latticework of mostly stretched octahedral Acanthite crystals, that may have spinel twinning, with abundant cubic crystals of the mineral also superimposed on these producing a refined and nicely composed small cabinet piece. These were undoubtedly Argentite when formed higher temperature conditions; however, they revert to Acanthite at lower temperatures (surface conditions). The piece displays a handsome gunmetal gray color and metallic luster. Notably, this is complete all the way around and equally dramatic on both sides. ex Robert Nowakowski collection
