The fine silver overlay provides a dramatic contrast with the black obsidian in this classic Los Castillo design from the golden period of Taxco jewelry design. This necklace is so very versatile and can go from very formal business attire to your weekend wardrobe. Black never goes out of style. This necklace has been faithfully reproduced in fine 970 silver by Gildardo Juarez who is a master silversmith and an instructor of the art. His grandfather worked for the legend Fred Davis and he follows the tradition of high grade workmanship.
