The hoop earrings are made of sterling silver and the pattern is on both sides of the earrings. The earrings are oval and measure 24 millimeters long and 18 millimeters wide. They are hollow on the inside and weigh 2.2 grams. I will provide a nice earring box for them. These are white gold and are not tarnished. The color you see in it is just the refection of my skin when taking the photo.
