A pre-owned diamond exchange platform. Inspired by this article recently on HN: http://news.ycombinator.com/item?id=4535611

During these hard times, give people a platform to sell their existing diamonds at a higher price than what jewelry stores are willing to pay. Disrupt the "estate jewelry" market specifically in the diamond space by bringing forth a dedicated Ebay type site that also includes appraisals (automatic/electronic?) as a separate fee. This would encourage people to sell all those diamonds that's been stored in safe deposit boxes waiting to be sold.

I'd thought about this as well, turns out there is actually a thriving marketplace for pre-owned diamonds on Craigslist. It kind of blew my mind that at any given point people are selling ten thousand dollar diamond rings on Craigslist.
