This thumb-size nodule of opal has been polished on one surface to highlight its intense opalescence in purples, blues, and greens. The best color is limited to about 1/3 of that surface, although spots of color are visible on several sides. The image does not do this justice, as the variety and play of colors is not captured by my camera.
