A dramatic cabinet, combination specimen from the famed basalt flows of Rio Grande do Sul and the Duncan Elliott Collection. Four large calcite rhombs to 3.7 x 3.5 cm are set on glassy, vivid purple amethyst crystals. The calcite rhombs have an interesting overcoat of sparkly, cream-colored, drusy quartz. Another generation of smaller, colorless calcite rhombs is attractively sprinkled on the amethyst and the larger calcite rhombs. Choice material from this noted locale.
