Most Mexican jewelry found today was made between 1940 and the present. After 1947 Mexican sterling is marked "Made in Mexico" and "sterling" and/or the mark "925" or "940". Between 1947 and 1979, the items also have an eagle stamp. This lovely bracelet, circa 1950's, has all of the above as well as the maker's initials. Composed of 5 gently curved links, each 1 1/2" in length connected by oval rings, the bracelet measures 7 1/2" long. Each link is adorned with a round green/blue cabochon stone. I am not sure the type of stone; it could be turquoise, calcite or nephrite jade. The bracelet fastens with a secure push-in type clasp. The item is stamped with a circular mark "Sterling 925 Hecho En Mex" and the silversmith's initials "SM". SM could denote Serafin Moctezuma, a noted craftsman, who copied the work of famed William Spratling. My research shows Moctezuma's mark was conjoined initials, however the SM on this bracelet are separate. It also has the stamped eagle #1 mark which denotes Mexico City. The bracelet is in excellent vintage condition with some scratches on the stone cabochons. The sterling links, rings and clasp show nice age related patina which I have not touched. A super piece in a timeless design.
