Bought these at an auction. They have 14 K RTI marked on both gold clasps. They look close to round but not completely. Very high luster. They are gritty on a tooth test. First and end 2-3 pearls are hand knotted middle is not. Necklace is 18 inches, bracelet approximately 7 inches. Approximately 4MM in size. They do have a mirrored look. I don’t think they are round enough to be Akoya pearls. So I am thinking a set of freshwater pearls. Am I correct?
