48" gold filled watch chain with slide and clip style clasp. It is 24" if you wear it doubled as a necklace.
The slide or slider is about 3/8", matte gold plated, with 4 tiny seed pearls. Both the clasp and slide test as 12K gold plated. The chain is a rolo style, gold filled and difficult to test accurately. There are four darker areas near the clasp end, each less than 1/2". I have tried to show these in the photos,and they are much less noticeable in person.
The slide or slider is in excellent condition and moves freely. This pretty chain dates from about 1900.
