NOTE: The duette (or double clip) style brooch increased in popularity in the first half of the twentieth century; they flourished during the Art Deco and Art Nouveau movements due to the use of symmetry of organic designs. Due to their versatility they can be simply worn as an eye-catching single brooch, whereas the two matching brooches could be utilised as collar clips, hat clips, shoes clips, and hair clips.
