mother-of-pearl lampshade suspension in the shape of a flower corolla

Pretty suspension in mother-of-pearl circled with gilded metal in the original shape of flower corolla. The pellets spin slightly (towards the orange) as one moves away from the edge of the opening. It must date from the 60s or 70s. It is in good general condition given its age: no broken or disused pellets, no broken welds, but it has various marks on some pellets, perhaps even original for some. The "electric and fixing" part in plastic, which seems to me original, is complete (socket for bulb with large cap, cable, hook ring, piton cover) but I have not tested it... Perhaps it should be replaced for more security, easily found in a diy store. The lampshade is 29 cm larger in diameter (at the opening level), about 25 cm high. The cable is about 20 cm long. The whole weighs about 415 g including 320 g for the lampshade alone.
