In very good condition, particularly given the brooch's age. The emerald is a lively, richly saturated medium green, and very lightly included. There is some significant surface scratching to the front of the stone, with some small chips and further scratching on the reverse. The large old European-cut diamond is approximately E-F color, VS clarity due to some chipping around the girdle. The large marquise-cut diamonds are approximately E-F color, SI clarity. The remaining diamonds are approximately E-G color, VS-SI clarity with several VVS examples. The brooch is very well made, and the individual components move freely when worn.
