ANTIQUE JEWELRY
The guide: Kovels' Antiques & Collectibles Price Guide, or
Warman's Jewelry, by Christie Romero.
What's hot: Any type of signed designer piece (Tiffany, Cartier, Van Cleef & Arpels) or pieces that have a recognizable vintage style, like Art Deco, says Richard Brodney, owner of Brodney Antiques and Jewelry in Boston.
What's not: "It's always something somebody's grandmother had," says Brodney. "The grandmother, God bless her, she's 85 and tells the granddaughter, I'm leaving you this ring. It's worth a lot of money. And a couple hundred dollars is a lot of money."
