I thought it was worth a try here. I also put it up on craigslist.
I bought this from Wedding Day Diamonds for about $369. It's a 14k white gold four-pronged diamond solitaire pendant. It wasn't worn all that much. I'm asking $200 for it. I comes with the original box and everything. I will deliver it myself if you live around St. Paul or I can mail it to you.
I don't have any pics of it yet but it looks like this.
