The earrings are made of 14k white gold. This includes the post and ear backs. The diamonds are held in with four prongs. The diamonds measure 2.7 millimeters round and they have a total carat weight of 0.10cts. The diamonds have a "H" color and an "I1" clarity grading. The earrings weigh 0.4 grams and I will provide a nice earring box.
