Where to sell diamond ring?

Hello! This is my first time selling a jewelry. If you can check my profile, I'm looking for a buyer for my diamond ring.

History (if this helps): my ex bought it May 2021 from Ty Po Huat. Proposed, then we broke up last year din. He didn't want the ring back, and given na I lost some money din naman during our breakup, might as well sell it na lang so I can use the money to buy a few furnitures for my new place.

I checked pawnshops here in Laguna and they don't buy jewelry, pawn lang talaga (and the pawn value is too low for me). Ty Po Huat is also not buying back jewelry. I'm willing to travel to Metro Manila to get this appraised and eventually sell this. Could you recommend a place where I can sell this? As in sell talaga, I don't want to see it na din naman, just make it to a good use.

I know this is not an investment query but please help your girl out.
