Ooooo aaaahhh! I adore the sinuous curves of Art Nouveau. This is something any Victorian maiden would be proud to wear! 
BTW since I've only done some prehistoric metal clay work [before versions 2 & 3 & syringes, etc.], did you do the original in wax or some other mold? How did you carve it? Sorry if the answer should be obvious...but it ain't to me.
