It looks to me like three strands. Two baroque necklaces and one of round gumballs. The earrings alone probably weigh more than many of my pearl necklaces, lol. I'm figuring 40 mm length and silvery to boot! I wonder where these monsters came from specifically (I know they are South Sea generally). There must be special farms that grow these or maybe some farms set aside a portion of mollusks to grow humongous pearls.
