This is a rare and very collectible piece from DeLillo’s circa 1968. I love the large light yellow discs (which I believe are bakelite) and the white glass elements. This couture piece is from a line of 6 or less. It has a sort of mod tribal feel to it and the construction is a sort of woven style in the back. It is a great piece of fashion history. You can see an interesting article on 1stdibs: http://www.1stdibs.com/introspective/capsule_collection/william_delillo_mens_jewelry_1968/
Condition is Very Good- There is some darkening of the bakelite under the white beads on the discs but not seen on. The other aspects are original like the two areas where you see a yellowed string sticking out where they tied the elements together. These are small and on the back neck area and back of one woven bead area. Another original aspect is one bead which is poured not round and looks half but is really originally flawed as it is smooth all the way around. Again a small detail.
William de Lillo was a major vintage fashion jewelry designer from Belgium who immigrated to the Unites States. His jewelry was often one of a kind, couture, runway pieces, or limited edition. He worked with many exclusive clients producing such pieces. Those patrons include Elizabeth Taylor. During the 1950s he worked for Cartier, Harry Winston, and Tiffany. In 1967 he started the House of de Lillo with Robert F. Clark. Clark had formally designed for Miriam Haskell. While living in France the 1970s they continued to produce jewelry for fashion houses like Yves Saint Laurent and Schiaparelli.
