Good question... It is clearly at least very much like one, but there are minor differences which are concerning when combined with it not being marked. On the ones online that are marked on the bowl I count 9 lines on each side of the leaf, where yours has only 8, for example.
looks like the markings were on the handle very nice find I have a tiffany ring I found that looks like it got hit by a lawn mower.......... Great find!!
