Erté 14k Gold/925 Silver Art Deco Necklace/Brooch Diamonds Mother-of-Pearl

Thank you for considering this limited edition designer-signed necklace by Romain "Erté" de Tirtoff, the father of Art Deco. This fine necklace adapts his earlier Rainbow in Blossom from a painting into 14k gold (both yellow and white) and sterling silver with eighty diamonds and mother-of-pearl. 
The necklace is partly constituted by a multitude of small flowers in white and yellow gold accented by 80 round brilliant cut VS1-VS2 F-G color diamonds weighing approximately 3.2 cts total weight. 
The centerpiece of the necklace is a stylized woman's face carved in mother-of-pearl in the center and is accented by an individual diamond adorning her forehead. 
The back is signed "Erté." 
This centerpiece can be detached and worn as a brooch. 
The necklace fastens via an open box clasp with a safety. The brooch fastens to the chain via invisible box clasps with safeties. 
Numbered "#14/250" on the back. Stamped "CFA 14k Ster" on the back.
