You are correct! I saw those pieces (there is a brooch and earrings as well) completely by accident at the Legion of Honor in SF about 7 or 8 years back. I was there to see a DaVinci portrait and it was crowded so I went to look at some jewelry exhibit. I was stunned to see them in a case! They are gaudy gold with emeralds and diamonds – BIG, too. And yes, apparently a consolation gift for losing the role of Scarlett.
