This is a very long 42″ necklace that can be worn as a long single strand, or a double strand, or as shown in the video as a triple strand. Although it has a spring-ring lock you won't even have to use the lock in order to wear this as a single or double strand because it will slip right over your head. You will only need to use the lock when you wear this as a shorter, triple strand look. This necklace has a continuous design all the way around, which is a simply elegant look. This necklace has continuous 5mm round synthetic, man-made “diamonds”, which are just under a half-carat each, set into an almost invisible bezel setting. The stones are placed pretty close together, only separated by two tiny loops, so when you wear this is looks like a continuous strand of sparkle!!! The base is always sterling silver and that can come sealed in this rhodium-platinum finish, a yellow-gold finish, a rose-gold finish and a black-rhodium finish. Call or email us if you do not currently see your preferred finish posted on the site – we could be out of it, but might be able to custom order it in for you.
