I think that would be gorgeous! Like others here, I am also matchy matchy.
I would for sure get the ring. If they have earrings, maybe try some on while you are there? I know your budget is $14K max, so maybe see if the mini size might look good with your pendant and ring.
I think your metal is RG, so I think there are mini RG pave earrings. If you don't like them or if that brings you over your budget (I don't recall how much the ring is), try the mini RG metal with the ruby center. I know rubies are not sapphires, but the stones have the same red blue understone, so it might be okay. Plus, the ruby is so tiny it might be a nice little accent to enhance the pink. Both the RG and the flower design will bring it together. I can almost see that combo in my head, but maybe try it to see if it really works in real life.

I do think mini earrings look really tiny worn alone, so think it that scenario bothers you. With your pendant and ring, I think it will look nice as an accent piece. Just a thought. I love Frivole so much I could drown in it!
And by the way, don’t panic buy. 5% against your $14K budget is $700. That is not going to make a difference in what you buy. But when you are ready and 100% sure. Impulse or panic buying leads to regrets in my opinion.
Congratulations on your new piece! I'm so excited for you!
