To me it seems very obvious from your latest close up photo that there are a number of button pearls. I had never noticed those previously.
This necklace is turning out to be much more interesting than I had ever expected.
Initially, from the photos of Queen Mary wearing the necklace, I assumed that the pearls were all round. Yesterday, I was delighted to see some drop pearls. (I confess, I have a weakness for drop pearls).
Now, I see a number of button pearls.
Many thanks for such an interesting photo. How I wish I could view the reverse of this necklace to see how the setting has been made! -But that is a technical issue.
