This is a really beautiful necklace, it's made so very well, the diamonds and dog bone will not fall out/off, the designer really secured them perfectly, the lock is very sturdy, I am not worried about it falling off. The dog can wear it everyday and it will still look beautiful. The diamonds really sparkle, the picture is accurate. This necklace is made better than most of my expensive costume jewelry. You will be very happy with this necklace
