Ceramic and 18K Gold represents the fusion of a 21st century material with the inspirations of a 20th century art deco movement. The unique usage and combination of these materials is ground breaking in fine jewelry design. This elegant 18K Yellow Gold and Black Ceramic Rectangular Locket with rounded corners and diamond accents is presented on a 32" small open-link chain. It is the perfect piece for a contemporary yet classic look. Each of our Ceramic Lockets bear an individual, unique serial number behind the inner frame that will allow you to know exactly when your piece was made. In the future, we will have an area on our web site where you can look up your serial number to know the date of manufacturing. Any ceramic locket without a serial number was made in 2015 and are among the first 100 in existence.
