The top of this Flag Harlequin Opal has good, even color play with compartments of rolling flash type ribbons of color, some of which are rainbowlike, and others being more solid and changing colors with different viewing angles. Lots of red, blue, green, and gold. This is the nicest opal I’ve cut to date.
