Rated 5.0 out of 5
1 Review

The necklace to satisfy all your Monday to Friday accessory needs - it can be worn at least 5 different ways. Adjustable to fit many necklines, sizes and styles, the Cosmos Convertible Collar is beyond versatile. Sleek and perfectly weighted for a cool, polished look, wear from work to dinner and into the weekend. And yes, this is the one and only necklace for your vacation getaway needs. 

To style all the ways, insert the toggle clasp into any of the open rings. Don't forget to try it backwards with the detail hanging down the back as well. :)
