What is the bracelet worn by Nicole Kidman in the movie Birth? - nicole kidman

Nicole Kidman has a beautiful gold bracelet with tiny beads that from his film "Birth hang" .. I thought it could be a vine, 'pearl', but it is not. Tiffany and Mikimoto pearls I found is that, where the film's credits jewelry. Has anyone seen or know where I can find?
