Cultured pearl, diamond and enamel necklace, David Webb

Designed as a scalloped collar of curved and rectangular links applied with black enamel, the center decorated with two flared segments of pavé-set round diamonds, suspending a baroque cultured pearl drop measuring approximately 25.0 by 16.6 mm., capped by small round diamonds, the total diamond weight approximately 4.50 carats, mounted in 18 karat gold and platinum, signed Webb, pendant detachable. 

Good condition with some very minor nicking and repair work to the enamel (seen only on very close inspection). The diamonds on the collar are approximately G-H color, VVS-VS clarity. The diamonds to the cap of the detachable pendant are approximately G-H color, VS-SI clarity. The very slightly silver white baroque pearl bears pink, green and blue overtones, good luster, and typical irreguarlities and blemishing. The clasp signed Webb.
