The necklace is made of 14 k yellow gold and the chain is a beaded chain with a lobster claw catch. The part that hangs down drops 2 1/2 inches. The chain has a bead you can slide near that catch so you can adjust the length to 17 inches long. This item weighs 3.60 grams. I will provide a necklace box. This item can be made in rose or white gold as well.
