In this case, we are attempting to design a ring that would work as:
The silver band Finrod made as an engagement ring for Amarië, but either never gave it to her, or she returned it to him when the Noldor left Valinor.
AND the ring Galadriel gives Celeborn when they agree to marry one another.
So, we've got Noldor gifting rings to their beloved non-Noldor (Vanyar and Sindar, respectively).
We should also keep in mind that Celeborn's name means 'silver tree', so if we stuck with a branches motif in the silver ring, it would be uniquely 'Celeborn'.
