Set of 2 mother-of-pearl wall lamps, 1970s

Pair of mother-of-pearl sconces and gilded borders, in the shape of a shell... They are decorative and will bring a vintage touch to an interior. Good general condition, but small defects to report, visible in the photos: one has a slightly darker scale at the base, probably due to the use of a bulb a little too powerful. 2 hooks on each side allow you to hang them or hang a string or metal rod to hang the sconces. A small notch in the lower part allows an electric wire to pass.
