Mexican jewelry often conjures images of heavy silver pieces with pseudo-Aztec motifs, set with green or black stones and ornamented with silver domes or balls to give them a primitive look. The style originated around 1920 in Taxco when Mexican silversmiths began making silver jewelry for the ever-increasing number of tourists. The arrival of Americans such as Fred Davis, who left medical school, William Spratling, an architect, and Margo van Voorhies from California amalgamated their sense of design with the traditional Mexican primitive style and helped create the sophisticated designs and craftsmanship of the silver industry so admired today.   This sterling silver parure set was created by the well-regarded silver house Beto in Taxco. The markings on all of the pieces identify it as having been made after 1935 and before 1948. Its understated design and a deep, rich patina, as well as the fact that it is a complete parure, add to its value.
