cabochon of rhodochrosite, from Argentina, with PLUMES! At one side, this outstanding stone features wavy bands of glowing pink coloration. And the other side has honey-colored gel (calcite), very gemmy & translucent, which contains several beautifully ornate plumes with ghostly fortifications. Separating the two zones is a scalloped band of cream, with fancy little figures that resemble buds.
