Gold tone necklace with six raised aventurine Murano glass cabs - 3 oval and 3 square. The necklace has an S-clasp and tassel consistent with the work of Henkel & Grosse for Christian Dior. However, this necklace in not hallmarked so I'm not sure if my attribution is correct. 

Condition is very good to excellent. The necklace is 15" long and has a 2" extender.
