I just love these adjustable necklaces, similar to the bracelets I have been designing since last summer. This design has vintage Swarovski crystals and sterling silver, and can be worn short as a choker, with the ends dangling down your back, or extend the chain, up to 32 inch maximum length. This sterling silver necklace is fully adjustable using a movable round silicone-lined bead that slides along the chain. Two round drops serve as a stop to keep the slider bead from slipping off the chain. The chains are high quality, made in Italy.
