Here is an antique necklace and long chain to be worn together. The necklace is made of silver plated metal and green galalith (French-German phenolic plastic). There are no markings. The necklace is at least 23 inches long. The long chain to go with it is 56 inches long. They would have been worn together. There is a very slight hairline crack under the metal on the right hand side of the necklace, but it is secure.
