Two necklace 20” and 24”

Both are in good condition and kept in a clean smoke free home. 20” X 9mm wide has crowns imprinted on one side of it throughout. I searched and could not find the brand. It has no brand mark . Not sure what the gold plating is. 24” X 6 mm has the Premiere Design logo - not sure what gold plating is. #Premierdesign #goldchain
