Vintage 1980s Napier Mother of Pearl & black enamel choker earrings bracelet set

Vintage Napier Mother of Pearl and black enamel jewelry set purchased in the 1980s. I am the sole owner. I saw this advertised on another site stating it was back onyx, it isn't. Dangle pierced earrings, 7 inch bracelet with latch hook (works fine), 16 - 18 inch necklace (adjustable) with lobster claw closure. This is silver clad jewelry. I stored in lined jewelry box the entire time. In very good condition.
