The big square earrings are made of sterling silver. The square shape is simple yet classic, that what makes those sterling silver earrings a perfect everyday earrings that can upgrade any dress and hair style. I gave the silver earrings a sand texture for a beautiful finish. The square size is 1.3x1.3cm (0.6.x0.6"), and they are 2.5 cm/1" long from your ear pierce.
