This is the very first design to come from Margot de Taxco, back in 1948. Margot was an important figure in the Mexican Silver Renaissance of the 20th century. She was the principle designer for Los Castillo before divorcing her husband, Anthony Castillo, and beginning her own line, Margot de Taxco. This is design #5100, as stamped with the hallmarks on the back. The sterling silver is hammered with smoothly polished, thick edges in perfect contrast. The design allows for a heavy patina on the hammered inner design, furthering its dynamic dimension. The wave-like design continues all the way around the necklace and hides the clasp on the very back, where the waves meet. The necklace measures about 14 inches around. It tapers from 1/2 inch to 1 5/8 inches at its widest point.
