Saw these as part of a listing that specified the pearls were not tested to determine whether they were real or fake. Any thoughts? I haven't looked at enough pictures to make a good guess. My initial impression was that they might be too round and the knots looked too big (though the size is given as 5mm, so it may be perspective). But I have also been astounded by the number of times folks here have said pearls look "eggy" and I just can't see it. No clasp as it is a long endless rope, so that doesn't give any clues. It looks like there might be some marks on some of the beads, but I can't tell if that's just (a) reflection or (b) wear & tear. Input is much appreciated -- I am trying to improve my eye!
