Last Christmas, I bought my SO a string of pearls (necklace). She doesn't like wearing them because they are too long and fall awkwardly over her chest, but too short to "double up". These are real pearls, so I paid a pretty penny for them all, but what can I do about it? Can I take them to someone to make the string shorter? There is no clasp, and it is simply just a string of natural white pearls.
