A new Harmony Bangle from Hemmerle featuring two aquamarines (26.16 + 24.93 cts) set in textured aluminium. Hemmerle's Harmony Bangles are renowned for their almost seamless mechanisms engineered to twist to open. Examples can be found in the permanent collections of the V&A in London and Cooper Hewitt in New York. The unusual light blue colour on the metal has been developed by Hemmerle in their Munich atelier through years of experimenting with aluminium's colour variations.
