Silver-Topped Gold, Sapphire and Diamond Brooch [ 黃金鍍銀鑲藍寶石配鑽石別針]
Extraordinary Jewels from the Collection of Cecile Zilkha
Silver-Topped Gold, Sapphire and Diamond Brooch
Featuring an oval-shaped sapphire weighing approximately 60.00 carats, framed by old mine-cut diamonds, accented by rose-cut diamonds; circa 1840.
In good condition, with wear and discoloration to the mounting, commensurate with age. Silver-topped gold mounting later rhodium-plated. The sapphire is a medium slightly violetish blue color, moderate color zoning, slightly included with several fingerprints under the table and scattered inclusions near the pavilion, not readily apparent when worn. The 14 old mine-cut diamonds estimated to weigh approximately 25.60 carats are approximately I-K color, VS-SI clarity. The 12 rose-cut diamonds weighing approximately 0.15 carat are of decorative quality. With fittings for wear as a clasp or as a pendant. Additionally fitted with threaded tube for mounting to another element, which is no longer extant. Dimensions approximately 1¾ x 1½ inches. Accompanied by AGL report no. 1106186 dated January 20, 2020 stating that the sapphire is of Ceylon origin, with no indications of heating. Please note that this piece closely resembles a brooch from the collection of Mary, Princess Royal and Countess of Harewood and only daughter of George V and Queen Mary, that was offered at Christie’s London, October 7, 1970. Please note that the brooch could also be worn as a centerpiece of a diadem, as seen on Princess Mary on page 90 in Famous Jewelry Collectors by Stefano Papi and Alexandra Rhodes.
