OP said the pearls were 5-5.5mm approx, and the necklace very short, 14 1/4 in, a choker, I guess. He hopes to list these on ebay at some point Appreciate hearing your thoughts now that the additional photos are up. A number of you are way more knowledgeable about vintage and Miki than I am. But these do look authentic to me. I did advise him not to clean the pieces.
