The earrings measure 31 millimeters in length and 11 1/2 millimeters wide. The earrings are made of sterling silver that has been black rhodium plated. The post and ear nuts are also plated. Each earring has 26 round black diamonds that are prong set. The total carat weight is .49. just under a half carat. The earrings dangle and the lowest three points on each earring dangle also. The earrings weigh 4.6 grams and I will provide a nice earring box for them. The diamonds are heat treated to make them look totally black.
