David Webb’s only lot at the auction, Lot 1625, titled, “Cat’s Eye Moonstone, Ruby and Diamond Brooch, David Webb,” sold without any difficulty, registering an enhanced price of HKD 200,000 (USD 25,788) over the upper estimate of HKD 160,000 (USD 20,630). The centerpiece of the brooch is a large hemispherical cabochon-cut cat’s eye moonstone, weighing 60.00 carats, with a distinct chatoyancy, surrounded by a narrow layer of prong-set circular-cut diamonds and a broader layer of cabochon-cut rubies, and an outer discontinuous layer of prong-set circular-cut diamonds, set against the line of seperation of two cabochon rubies. Since there are 20 rubies in the brooch and 20 lines of separation, there are 20 circular-cut diamonds in the outer discontinuous layer. The central moonstone and the inner layer of diamonds are mounted in platinum, and the rubies and outer discontinuous layer of diamonds are mounted in 18k yellow gold.
Hence, in general signed lots at the auction performed reasonably well compared with other lots.
