Where can I sell 3 carat Tiffany diamond ring?

Based on the eight questions you asked -- all alternates -- you have a diamond ring that you want to sell.

Your first job is to pay for a certification of the diamond and the setting. You can take it to a certified gemologist -- not a local jeweler for an appraisal -- who will document the quality of the stone according to its cut, clarity, carat weight and colour.

With this information, you'll have a better idea of the value of the ring. Then, you can sell it privately, consign it, pawn it or sell it outright.

(You can buy a 3-carat diamond today from Blue Nile and spend from US$22,000 to US$28,000.)
