Rare Mexican Modern Silver Jewelry Suite Caviar Model William Spratling

A rare four-piece suite of Mexican Modern silver jewelry suite circa 1940s from Taxco, Mexico and crafted by William Spratling (1900-1967), an American designer and entrepreneur who established his silver studio in Taxco in the 1930s and revolutionized the silver design industry in Mexico by producing high quality silverware with modern designs.
The model of this set is called Caviar and belonged to the first phase of the design. It was hallmarked with variation 3 for the period of 1940-1944. The set consists of a choker style necklace, a bar brooch and a pair of earrings with screw-clip. The design of the necklace consists of simple and repetitive motif of round silver beads, which resemble caviar (in a slightly mischievous way), with innovation hidden chain links and a box clasp. The bar brooch echoes with a row of six beads of the same size with the pin in the back, while the earrings feature a much larger hemisphere ball. All pieces bear the branding with the necklace hallmarked SPRATLING MADE IN MEXICO-VS, SPRATLING SILVER.
The necklace has a total circumference of 18". The brooch is 1.75" long and the earring is about 0.5 inch in diameter. Total weight is about 122 grams (3.92 troy ounces).
