This 10k yellow gold chain and pendant is perfect for that "Sweet Sixteen" gift. The diamonds are not large but respectable and the chain is a good length 17 inches. The pendant is marked on the spring ring but very faintly. The pendant is also mark but sort-of smeared. But they are marked. The chain is very fine. In excellent condition. The pendant is 3/ 4 of an inch and 1/4 wide. For you from the Wheat State Kansas!
