Vintage, French, Louis Rousselet, or Rousselet order style, pate de verre brooch.

Beautiful, French, Louis Rousselet, or Rousselet style brooch. The glass components are very much in the style of Rousselet, however the back of the brooch looks different from other Rousselet pieces I've seen as they are not wired onto a brass grid but wired onto a metal mesh. The back of the brooch is marked ‘Depose‘ which confirms it is French. The condition is good, although there may be a leaf missing and order one leaf is chipped at the very end. It measures 7.8 cm, or 3.1 inches, long.
