There's a good yeoman jewelry repair and cleaning guy with 30 years' experience here in Cedar Rapids (Iowa). His name is Randall Patterson, phone (319) 366-6611. His work is guaranteed and modestly priced.  He fixed a broken clasp on my wife's fine gold chain; brought in on Memorial Day, picked up this morning. Randall's old shop downtown was sunk during the great Cedar River flood of 2008, so he works at home.  Call ahead.

I'd add him to Craigslist, but frankly the details of that hypermundane task are more time than I'm willing to invest.
