They have the
3 tennis bracelets- 1 blue and 2 diamonds which have been worn by Silvia, CP Victoria, Madeleine and Louise. They have the
3 strand pearl bracelet with a pearl clasp which has been worn by Madeleine CP Victoria and Louise, the
Bernadotte Diamond Bracelet which has been worn by Silvia and Louise, the
2 strand pearl bracelet with crown which has been worn by Silvia and Madeleine, the
2 row diamond bracelet with square clasp which I have seen on Silvia and I think CP Victoria and the
Zig Zag Diamond Bracelet which has been worn by Madeleine, Lilian, Louise, CP Victoria, and Silvia.
That's what I can think of off the top of my head right now.
After looking at it photos from the trip again I think it is very likely it is the Crown Pearl Bracelet. She wore it a lot during that visit.

this photo makes it look like there is the monogram on it.
