A sort of aigrette/bandeau tiara in the form of two feathers tied together with a diamond bow.
A classical-looking diamond tiara with a large diamond feather, which is detachable, coming out of the center. This is in stark contrast to natural feathers, which were very popular to wear in the hair during the 1920's.
What I think has to be the cutest tiara in all of God's creation, a diamond owl wearing a little ducal tiara, and a collar with a chain, to make sure he doesn't fly off of the tiara frame.
