The earrings are made of 14k yellow gold and have posts and clutch backs that are also 14k yellow gold. The emeralds are round and measures approximately 4 millimeters. The emeralds have a medium green color not to dark not to light. The emeralds have a lot of inclusions in them but they look good. The stones are held in with four prongs and the total carat weight is .54. The item weighs 1 gram and I will provide a earring box with the earrings.
