Vintage Sterling Silver Turquoise Zuni Watch Band by Effie Calavaza. This beautiful and expandible watch band is in great condition. It depicts the signature snake design by Effie Calavaza. It is stamped Effie C. on the back and has blue turquoise and red coral stones set bezel style. The blue stones are 3/4" and the red ones are 3/8" and weighs 24 grams. I'm not sure of its exact vintage but looks to be mid 20th century (1940-1969).
