Mother-of-pearl hanging lamp

Nice mother-of-pearl hanging lamp surrounded by gold metal. The lozenges are white and the round-shaped ones have been coloured in coppery orange. The lampshade must date back to the 1970s. It is in good general condition given its age, but has two or three broken welding points, defects totally invisible and which do not call into question the solidity of the whole. The "electric and fastening" part is complete (sleeve, cable, hook ring, electrical connection dominoes) and seems relatively new, probably replaced... The set has a few small spots and traces of use, or origin. The lampshade is 25.5 cm larger in diameter and about 15 cm tall, the cable is about 25 cm long. The socket is intended for a light bulb with a big nerve. The whole thing weighs about 310 g. The first photo was taken with flash, the others without.
