Viewed under SW ultraviolet light, this combination of blue-fluorescing diopside and yellow-fluorescing norbergite (same specimen as in photo DPS18a) is unusually attractive. Such "half-and-half" specimens, rich in both minerals and nicely separated into blue- and yellow-fluorescing portions, are uncommon.
