Not sure about the strand, but there are a few pearls there with very, very deep circles; I absolutely LOVE those oddities!
Impossible to find more then a few at a time; who knows why...
If you unstrung the rope, try those strung one after the other as a bracelet - I find the look very surprising for pearls (the gap between pearls gets confused with the deep circles - as if you had some impossible pear roundels, only more interesting).
Just a thought.
