Great input, you’ve touched on so many points that are on the back of my mind! I always considered WG and YG to be best choices especially for large pieces!I love the Frivole collection and have the WG pave BTF ring and matching earrings. It's my favorite of all VCA collections, and the pave makes the piece pop. I wear them very casual.
If it were me, I would sell the gold pendant and get the large pave pendant (no need to have two Frivole pendants). It is very pretty especially if you wear short pendants. The large is not that much more in price than the small, but size-wise, it's a big difference to me. If you cannot swing the large, then for sure, I would get the small in pave.
For metal, unless you really really love RG, I would get YG. RG is trendy now hence it feels fresh. But RG was also once fashionable but faded (you could not even buy RG pieces as part of regular stock). Yes, now it's back, but I think RG may fade again. YG, WG, or platinum will always remain in my opinion. And for me, I never mix metals, so just something to think about. For me I would choose the WG. It's all preference of course.
Regardless of metal, I think you will love the pave... Frivole sparkles like crazy!
Good luck to you!
I wear diamond studs everyday so wasn’t worried about matching although frivole pave earrings in WG are on my list and matching is something to consider.
Due to availability issues with VCA now my SA doesn’t have any of them in store to try and compare but promised to meet with her this week as she will have one Frivole pave with pink sapphire in to try!
I would love to swing the Large size but it’s very close to the earrings on my wish list! Ahhh so many decisions

enjoy your pieces, they are gorgeous !
