I have owned this necklace for years. It has never been worn. It is immaculate. The 1984 Panda Coin is 22K, 1/2 Troy oz, weight is 15.55 grams, the total weight of all is 28.50 grams, see photo. The 20 in diamond cut rope chain, with a fine lobster claw catch, and the rope bezel are 14K, see pics. Thanks for your interest..
