For your consideration is this very nice Chinese export necklace likely from 1930s. It is a choker length, with a large 1 inch sterling silver bead with reposse Dragon on it. The bead is marked silver, which is the old hallmark and is often 900 silver. The bead tests sterling silver with nitric acid.The clasp is a silver filigree clasp marked S925 on the clasp tongue. The serpentine beads or celadon jade (commercial name) beads are 12 mm each. Total length is 16 inches, meant to show off the silver bead right on the neckline.
Good condition showing no problems. Looks very nice when wear.
