The bracelet is most defitently from the Emerald Pauvre set, and the earrings are most likely another setting of the original pauvre earrings. The broach isn't apart of the original pauvre, but it's been in the family for some time.

I believe the gray pearls and white pearls are from the same set. I think she can interchange all of her pearl earrings with gray or white. There is also a formal diamond setting that can be worn and the bottom drop can be taken off for a daytime pearl and diamond stud......Lovely. I have always wondered if this was a wedding gift as she has been wearing these pearls since close to her marriage....
The design on the formal emerald and diamond bracelet is very simple, just stones set in a line. But when you look at the size of each stone it is so very impressive. The Dutch jewels seem to have a few designs like this. Im thinking some of the rubies also.
