Comment: A DRAMATIC and AESTHETIC CABINET specimen from the La Sirena Mine, Guanajuato, Mexico. Highly lustrous, translucent, modified stepped-growth calcite scalenohedrons to 6.0 cm are beautifully scattered as a discrete crystal or in clusters on a superbly contrasting matrix covered with lustrous, brassy pyrite crystals. This striking, large piece is essentially pristine, with only the slightest edgewear on the bottom front of the isolated calcite crystal. This mine is on the same vein as the famous Rayas Mine. EXCELLENT material from the Dave Stoudt Mexican Collection.

Minerals: Calcite (CaCO₃) Pyrite (FeS₂)
