My girlfriend would like to sell a silver heart necklace with a small (~0.10 ct) diamond. It was purchased ~6 years ago for ~$400 on clearance somewhere. That's about all the information we have about it. Questions: What's the best way of going about selling such a thing? Ebay? Does it need to be appraised? How much does that typically cost? We're in Los Angeles.
I have a big book of old Magic: The Gathering cards. I've been told they're worth a decent amount, but have been out of touch with the game for maybe 6 years. What's the best venue for selling these? Anything relatively painless? Do I need to buy a price index or something?
