The earrings are made of sterling silver and there are two diamonds set into each earring. The diamond in the center of the earring is on a hinge and it will shimmer with little movement. The total carat weight of the diamonds is 0.02 carats. The diamonds have a "G" color and an "SI 2" clarity grading. The earrings have a silver lever back. The earrings measure 19 x 13 millimeters and weigh 2.6 grams. I will provide a earring box.
