This is a very nice old chain and slide. The slide is solid 14K gold. Tested in multiple places and I gave it a really good, deep rub to verify. The chain is gold filled. If you hold it by the clasp and let it hang straight down, it's length is 25. It weighs 16.9 grams total. There is a very nice and colorful natural opal along with two pearls in the slide.
