Ametista do Sul, Alto Uruguai Region, Rio Grande do Sul, Brazil
Cabinet - 14.1 x 8.9 x 4.8 cm (5.6 x 3.5 x 1.9 inches)
Weight - 170 grams (0.37 grams)

From the surface of a nearly flat basalt matrix rise numerous tabular pseudomorphs of quartz after anhydrite. The largest of these pseudomorphs measures 4.4 cm (last photo). A carpet of fluffy snow-white mordenite sits at the base. Minor calcite is also noted (fifth photo). A few of the pseudomorphs are incomplete but this is not a detraction on this specimen. Displays well as shown in the first two photos on its natural base.
