Ever sold an engagement ring?

[KAdams4458]

I have a ring floating around still from a woman I tried to marry years ago. It bothers my wife a bit, as if it's still some tie to some other woman, but really, it's just a ring. What she doesn't understand is that selling a ring is an even bigger PITA than buying one. I've gotten in to researching the process a few times, and I have to say that most of the information on the 'net regarding it is terrible. I always end up tossing the thing in the back of a drawer and forgetting about it for a while.

You all seem like bright people, so I'll ask for your ideas. What does one do with, say, a .45 ct old mine cut diamond mounted solitaire style in a yellow gold, authentic victorian era ring? The real problem is that it's not just a diamond ring, it's over 100 years old, and the antique market is much more elite, and far more subjective than the market I'd be in if this thing were some recent Tiffany ring. I don't need top dollar for it, but I'd like to get a decent amount out of it. All proceeds, of course, will go to buying jewelry for my wife, since I'm sure that will make her feel all warm and toasty. (Shhhsh! I might be tempted to buy a Mercedes part or two as well, but none of you know anything about that.)
