How? You don't usually buy diamonds for yourself, so the person who understands the diamonds are a scam does not have to be the same person who is attracted to diamonds.

Theoretically you could spend the same amount an some insanely huge used diamond.

But that doesn't dictate how much you're supposed to be paying for each individual diamond. If you have a "proof of love" budget of $6000 you could just buy five used diamonds instead. You could then start an arms race with other married couples and claim they don't love their spouses, because they only bought them a single diamond.

Edit: I checked and multi diamond cluster rings look way more impressive and make single diamond rings look cheap and icky.

> Basically the only reason someone would have to sell their wedding rings are divorce or some other downturn.

That's why your shop should only sell the weddings rings from people who had a long and successful marriage and died peacefully in their sleep at age 95.

Just gotta market it right. Maybe section off by length of marriage and dissolved by death or divorce.

A 60 year marriage, ended by death of one spouse shouldn't be unlucky. Especially if it was actually the death of both spouses in some tragically romantical way.

My wife wears my great grandmother's ring. I thought that she would not be interested but was elated when I discussed the option. When I was talking about marriage with my parents my mom mentioned that she had a couple rings I would be welcome to, but then mentioned: "one is from a very long and happy marriage, that would probably be best, the other...".

After you receive it, you can take it to a jeweler for confirmation. If it was falsely represented, eBay should back your return claim.
