22kt Gold plated Copper Brushed Link Chain sold by the foot measures approximately 16mm for the Circular shaped Links. The 22kt Gold plated chain has been hammered then brush finished for added brilliance. The thickness of the links is 1mm and each link is soldered to ensure a secured link. Each chain link has been treated with an "eCoating" to supplement the durability of the metal to environmental factors such as oxidation. This coating is non-toxic and will retain the original luster of the metal. The metal will stay bright longer.
