Impressive 3.9" X 3" Chased repousse silver antique Chinese 19th Century lock with Qilin and boys on front, and inscription on verso. Lock metal has not been tested but appears to be silver with worn off gold vermeil. It is signed. The coral bead is a whopping 25 millimeters in girth, X maybe 23mm, hard to measure because of the bead caps. Bead caps may be removed by request for accurate measurements. The coral bead and bead caps weighed alone, separate from the entire necklace, weigh 28 grams. The turquoise pieces weigh 13 grams and 9 grams, and measure 16.5mm X 24mm.
