Co-written by antiques expert, Judith Miller and costume jewelry specialist, John Wainwright, DK Collector's Guides: Costume Jewelry traces the history of costume jewelry from ancient times to the present day. It also explains how social and economic developments, changing fashions, new materials, and manufacturing techniques, as well as the haute couture houses of the 1940s and '50s have influenced and inspired the industry. Over 1,500 collectible pieces are presented in full-color, in a catalog-style layout, with prices and sizes clearly displayed below each one. There are profiles of 20 major international designers and factories, including Joseff of Hollywood, Trifari, Miriam Haskell, and Christian Dior. In addition, pieces by 80 lesser-known names are displayed and priced, and there is a gallery of unsigned collectible pieces. Contextual notes explain the features that make the pieces desirable, and there are tips on what to look out for when buying. "Hot" collecting fields, such as Bakelite and Christmas Tree pins, are featured throughout. The book also includes a glossary of materials, a list of designer's and maker's marks, and a directory of specialized dealers.
