This post earring has two articulated pieces. Oxidized silver (darkened) and 22k bimetal. Overall length is 1.25 inches.
Bimetal: A layer of 22k gold with a bright yellow color is bonded with sterling silver to form a sheet of precious metal with two distinct surfaces. The 22k bimetal is two to three times thicker than gold filled products giving it more luster, flexibility and durability.
