Push Present

Needing your help! I recently had a baby and my husband wants to buy me a push present. My budget is no more than 2k. I can't think of anything....I want it to be jewelry so it will be something to last forever. Here is a background on my jewelry collection I already own:

2 Cartier love bracelets
Love necklace
Trinity ring
Stackable pave bands
Chanel ultra ring

I love Jennifer Fisher jewelry but she is so overpriced I could get something designer with more value for the same price. I also was thinking some of the more inexpensive van cleef.

Baby's birthstone is ruby btw

Any suggestions? Any advice is appreciated!
I would choose something with the baby's birthstone with the idea of giving the piece to the child when he/she is grown. If the baby is a boy, the item can still be gifted to him to give to his bride/wife when she has their first child. If the baby is a girl, it's a no-brainer. It will be an heirloom either way….
