Best place to sell jewelry

Hi everyone. I have some jewelry from an engagement that didn’t work out a few years ago. I am at the point where I am ready to part with these items and I’m looking to see where might be the best place to sell them. I’d rather avoid pawn shops. I understand I am not going to get what I paid, but they’re just gathering proverbial dust at this point. Are there any reputable places that would give fair amounts (understanding fair is subjective)?

Thank you in advance !
