Hi, I received a nice pearl necklace for my birthday and went in to the jewelers today to get it threaded. It was given to me not threaded in case I wanted to exchange it or choose another lock for it. I was asked if I wanted it knotted or not. This surprised me as I thought it standard procedure to make a knot between each pearl. The saleslady expressed a strong preference for not knotting, she liked that look better. Since I had not given this any thought previously I would like to ask : what do you prefer ? Do the two varieties give different style impressions ?
