Jewelers in NYC to repurpose engagement ring

I have my old engagement ring & band. I have gotten both bigger to fit my middle finger. The band I wear upside down and honestly you can’t tell. The engagement ring is more obvious lol. My sister recommended making it into a pendant. It’s 1 ct yellow diamond and 1 ct total in smaller diamonds across the ring. I was thinking of making 2 necklaces. A pendant consisting of the yellow diamond with the halo. The second, maybe a similar sankofa design with the remaining diamonds.

LF: advice on jewelers in NYC, if a 1 ct is big enough for pendant, & other ideas for the smaller ones. I have reached out to one guy in Queens but didn’t feel like it was a match
