Silver and mother-of-pearl earrings

I bought these in the summer of 2021 and worn maybe once, but they made of 925 silver and tarnish easily (I live in humid climate). If you don’t mind cleaning them frequently or know how to care for that type of jewelry - they are very pretty. I mostly wear gold and can’t figure out how to keep them tarnish-free. Made to look like Pasquale Bruni earrings but these are no brand earrings I bought on my trip to Eastern Europe. I had a label but lost it. It said made of 925 silver (rose tone outer layer) and pale pink mother of pearl. The pictures are taken after quick polishing, but you can see the tarnish on the backs and posts.
