Collecting vintage jewelry

I like collecting older pieces of jewelry like Avon, Napier and Cartier. I find them at thrift shops and yard sales. Pieces that catch my eye and seem to tell a story. I have yet to discover a "Tiffany" piece but I know it's out there waiting for me to discover it. These pieces are representations of the past and a different way of life. Who was the woman wearing the necklace? Was she going to a holiday party or just having friends to the house for a cocktail and social hour? A lot of vintage pieces aren't made of precious metals or hold precious gemstones but they have a quality and a richness not found in jewelry today.

What is the most exciting treasure you've found thrifting or at a yard sale?
