This antique key wire pendant is made using 18 (1 mm) gauge copper wire and genuine blue quartz beads. The pendant and the clasp are all hand formed by me with great care and joy. The pendant will come with matching chain. The necklace is about 29 cm - 11,41 inches long with pendant and clasp. Lenght is customizable upon request. All my items are made in a pet free and smoke free enviroment.
