My car stole my barrette

It's been over two years now since my car stole the beautiful blue tortoise-shell French barrette I received as a gift from a dear friend. I've pushed the seats forward and backward, stuck my hand into the crevices, searched with flashlight and tongs. My car regularly eats my trinkets; if only it would give back my lovely barrette... Similar but black barrette shown below.
