ANTIQUES ROADSHOW continues its stop in Providence, Rhode Island, where host Mark Walberg visits the Providence Jewelry Museum in nearby Cranston and discovers Providence once was the costume jewelry capital of the world. Appraiser Joyce Jonas offers a primer of the vintage "fabulous fake" jewelry market, including such famous brands as Chanel, Dior and Schiaparelli - all made in Providence. Appraisers at the Rhode Island Convention Center sift through baubles, bangles, beads and bric-a-brac to discover such gems as a much sought-after collection of 20th-century Remington ammunition-themed calendars; a remarkable set of prints by Rembrandt and Albrecht Durer, purchased by the owner's father for a song; and a 1923 bronze automobile hood ornament, crafted by Harriet Frishmuth, renowned American artist and student of Auguste Rodin, valued at $20,000 to $30,000.
