This is a stylish necklace by Simon Sebbag. The company has been in business since the early 1990's and this is one of his early creations. The necklace is a rigid chain (neck ring) with a large pendant. You can wear the neck ring by itself or with the pendant. The way it is designed it fits beautifully around the neck and the pendant lies in the center of your neckline. It is very comfortable to wear and will fit different sized necks. It measures 13" around and 15 3/4" including the opening. The neck ring has a chunky look. The pendant is 1 3/4" top to bottom and 1 3/8" wide. It is 5/16" thick so it looks quite substantial also. This necklace weighs about 44 grams and is in excellent condition.
