DId not last for a long time, that too with a very limited use. As some1 mentioned, the thread is just a thread. It broke off. Also the pearls were of quite inferior quality. I disappointed my mother, but more importantly I disappointed myself for getting her such a bad product.
Outstanding! My mother loved them. My father had given her a string of black pearls before and they were so cheap that my mom returned them to the store. I was nervous about ordering these off the internet. Sometimes you just don't know what you will get. She was VERY impressed! They were lustrous, quite heavy, and she wore them for days! An amazing value!!! I am glad we were able to find her a quality string of pearls at such a great price. I am now so encouraged that I will order myself a nice white strong of pearls from the same manufacturer. I know I will get a good value and Overstock's service was top notch. They arrived well before Christmas.
Very nice. This was part of a wedding gift to my wife and she loved it. Pearls not too huge or too small. I measured on ruler before I bought you may want to do the same. Very nice color and size uniformity. As far as toughness I can't really say yet as she has only had them for a few days. I would expect though that with care these would last. I'm very satisfied with this purchase.
