Diamond and ruby flexible platinum bracelet with central rings and cylindrical chains, 1930s-1940s. Pull out barrel clasp. 2001,0505.11. © The Trustees of the British Museum

This and the following bracelet illustrate the two approaches, one geometric, the other fluid and curvy, that ran in parallel in the later 1930s. This bracelet has a rounded three-dimensional feel with its central rings and cylindrical chains forming a loop at each side. The emerald bracelet (2001,0505.12) has a flatter, more rigid feel with its square-cut stones.
