Those gold square earrings are simple and classic jewelry that you can wear everyday. I gave the square earrings a matte finish with a sand texture. The earrings are made of brass and they are 24k gold plated (nickel free). The length of the gold dangle earrings top to bottom is 2.5 cm (1.0") including the ear wire. The size of the gold square is 1.3x1.3cm (0.6.x0.6")
