German kabirski diadema earrings pearl luxury modern dangle asymmetrical

a pair of diadema model Pearl earrings from German kabirski from the site it says "a delicate mixture of precious metals and combined together in these pretty droplet earrings. ... iridescent pearl sits closely in each one." The materials are stated as silver 925, Pearl 18K, plated gold, black rhodium, and white rhodium. They were never worn by me. The earring part is tarnished but I do not have the proper polish. The rectangle that goes in the ear I took a picture of it. Comes with its original lined velvet pouch and in the magnetic box.
