Care and Maintenance: Please care for your pet's new collar as you would your own nice jewelry. This collar is meant for special occasions only. The stones on this collar are prong set which allows for a much brighter sparkle and closer placed stones for a prettier look than rivet set stones. Prong set stones can come out easily due to scratching, rolling on carpet, or playing with other dogs. Please do not leave your new collar on your pet unsupervised.
