This diamond-cut sterling silver rhodium-finished Omega chain neck ring is ideal for showcasing your customerÂs choice of pendant. Omega is a chain comprising small metal plates aligned next to one another and crimped to an underlying mesh substructure to create a bright chain with lots of surface area but limited flexibility. Diamond-cut versions enhance the light-reflecting properties of the link surfaces. This necklace is finished with an easy-to-use friction clasp. Rhodium finishing provides a durable, tarnish-resistant finish. Because this chain is diamond-cut, its diameter size may vary slightly.
