The late 1930s and the 1940s heralded a true architectural movement in retro jewelry design. The best pieces balance the principals of architectural engineering and design, with aesthetic beauty. This bracelet is one such piece and is likely of American origin. Remarkably, this bracelet appears to be of fixed 'bangle' form when worn but fully articulates with each element gently undulating against the wrist. Of bi-colored design, it is composed of a series of ten sculpted rose gold links joined together by curving diamond-set white gold connecting links.
