Taffy Crosswire's necklace

Taffy Crosswire purchased an imitation sapphire necklace from Irina Katrina Von Hapsonburg, who claimed to be Archduchess of Moldavia. Muffy Crosswire is the necklace's current owner. She took the necklace to Treasure Caravan to have it appraised only to learn that the necklace was fake and there was never an Archduchess of Moldavia who goes by Irina Katrina Von Hapsonburg.
