I found a picture of Thelma Chrysler Foy wearing a very large diamond on her necklace but the shape is completely different from the pictures of the current Chrysler diamond. She also has a large diamond ring.



The diamond has been cut twice since it was owned by Foy taking it from 62 to 54.03 carats. I don't know enough about diamond weights to know whether 8 carats could account for the differences in the diamonds.
