With this vintage link necklace from the 1930s, the maker used curved links of diamantés in a tank-track pattern as the centerpiece. The jeweled links have rhodium-plated backs. A link-and-bar chain with a spring-ring clasp complete this Machine Age piece. Because this necklace was in my personal collection, I had it shortened. Its purchase includes four additional links, which are each about one-half-inch long. Scroll down to see some tank track bracelets, also by Schreiber & Hiller, to wear with this wonderful necklace.
