Vintage Stephen Dweck Rare Semi-Precious Glass Circle Link Faceted Onyx Necklace

Rare, vintage, Stephen Dweck Necklace with a mix of glass, semi-precious, and gilt elements - circular rings of blue and green sparkling glass, combine with rings of semi-precious stone, including tigers eye and carnelian, connected with intricate chased metal links, with large faceted onyx stone beads serving as spacers. Signed on the interior of the toggle clasp. About 24 inches in length end to end. The style reminds me very much of pieces Robert Goossens created for Yves Saint Laurent in the 1970s - with a distinctively Dweck-style stone work twist.
