Lindy's has a nice selection of different styles of jewelry, from silver charms to class rings to gemstone and diamond jewelry. She also repairs and custom designs jewelry by request, at a reasonable price. My sister got her class ring there, and a friend had a sterling silver earring crafted to match a missing one, and both were very satisfied with the outcome.
PROS: Repairs and friendly service.
CONS: Not a huge inventory and sometimes open hours are limited.
