Vintage very old dress shops clip

Product Name: Vintage very old dress shops clip
Can we have a beautiful beautiful dress clip that I acquired during an auction. Beautiful piece is very very old. I would say early 1900s. All their stones are intact in place heavy piece. The clip on the back snaps back just fine all in working condition even some flower detail is on the back. This piece is unbelievable certainly a collectors item there might be possibly in the back on the mid-a signature but I can't make it out it's some kind of stamping. This is in good vintage condition like all vintage it has somewhere in this piece is very old but everything shops looks intact.
