Just last week I traded 3 ASE's for a 0.4 ct. amethest marque (sp?) stone with two small diamonds, 14k gold ring. (It will be a birthday present for my wife) The jeweler was very happy to trade with me. So happy, in fact, it made me wonder if I got the short end of the trade. I have bought jewelry from this jeweler for many years and we have a good relationship, so, maybe she was doing me a favor. Either way... I am looking forward to the look on my wife's face on her b'day!
First find out what the market is for your silver, then go talk to the jeweler... maybe they will trade with you!
Best wishes to you and your future bride! May you enjoy all the joys and happiness I have shared with my spouse for the last 34 years!
