I have the great fortune of working for Christies and being able to see these jewels in NYC ALL day! I find it really interesting that in their catalogues and descriptions, they never refer to the pearls as South Sea or Tahitian when they clearly are. Even when they have a GIA cert. They will designate them as saltwater, though. It is just so amazing and gratifying to see the signed pieces by famous jewelers and be able to handle them. Please! If you are ever in NYC during a preview for jewels...next one is June 20 auction, Magnificent Jewels! Come to the preview 4 days before that! Ask for me if you get there. I would love to meet you.
