18kt Gold and Enamel Snail Brooch, Cartier, designed with a green enamel shell, full-cut diamond melee accents, no. 13706, lg. 2 1/2 in., signed.
c. 1970s and probably New York. Overall good. A couple of very minor "bruises" to enamel at bottom of shell, not obtrusive. The numbers are on the base of the snail itself, but the signature is on the catch to the pinstem.
