Congratulations to Isabella! She's looking wonderful.
But I agree, it's sad to see historic jewels leave the main line. This one reminds me (being Swedish) of the amount of jewels that has left Sweden for Denmark.
First with princess Lovisa, and then with princess Ingrid (leaving Ingrid's four brothers with less). So many of crown princess Margareta's tiaras have gone to non-reigning families, and now to a side line.
I had expected that in these modern days (with royals marrying commoners), tiara-borrowing and jewel foundations would be the new normal.
But I'm very happy to see Isabella in a tiara, it suits her and it looks good with the earrings!
