An extremely rare specimen from a one-time-find in the Daye copper mine, this gorgeous piece displays a cluster of Dogtooth Calcite crystals partially "crowned" by second generation Calcite.  The Dogtooth Calcite crystals are perfectly terminated artfully covered by a layer of shinny iridescent Chalcopyrite.  The second generation Calcite crystals are between transparent and translucent in white color, creating good color contrast with the Dogtooth Calcite.  The Calcite fluoresces a medium pink color under UV lighting (365 nm).  It is rare in combinations and beautiful in formations.
