Gold, Opal, Enamel, Pearl and Diamond Brooch (c. 1920)

“"Designed in Indo-Persian taste, the brooch is in good overall condition with gentle wear to the gold mounting and light chipping to several areas of the opaque white enamelling; the chipping breaks through to the gold ground in a few spots, but this is not apparent when worn. The shaped, openwork frame is centered by a semi-translucent black opal tablet (approx. 16.5 x 12.8 x 2.7 mm) displaying strong play-of-color with green and blue hues predominating while revealing a few flashes of orange and red. Completed by 6 small silvery white pearls, approx. 2.3 -2.4 mm, and 4 single-cut, near colorless diamonds of good quality, approx. 0.06 ct. Signed Cartier on the reverse." - Sotheby's”
