Christie's Hong Kong: The Pink Petal and a Cartier Art Deco Ruby Brooch
An 8.41 ct purple-pink diamond and a Cartier brooch from the platinum age lead more than 120 jewels in Hong Kong next month.
Christie's Hong Kong Magnificent Jewels Autumn sale on 24 November 2026 brings together more than 120 jewels. It is headed by The Pink Petal, an 8.41 ct fancy vivid purple-pink diamond ring, alongside a Cartier Art Deco brooch set with a 10.10 ct Burmese ruby with no indications of heating.
The sale
Christie's will hold its Hong Kong Magnificent Jewels Autumn sale on 24 November 2026, during Hong Kong Luxury Week, with more than 120 jewels, according to the auction house's announcement reported by Artdaily. The sale is part of Christie's programme marking forty years in Asia, and previews have toured Taipei, Bangkok, Beijing, Geneva and Shanghai before the Hong Kong view.
The Pink Petal
The headline lot is The Pink Petal, a pear-shaped diamond of 8.41 ct graded fancy vivid purple-pink, VS1 clarity, and described as a potential Type IIa stone. Fancy vivid is the strongest colour description a laboratory gives, and Christie's notes that only a small share of pink diamonds reach it. Rapaport reported a high estimate of HK$95m.
A Cartier ruby from the platinum age
For collectors of Art Deco, the more interesting lot may be a Cartier brooch centred on a 10.10 ct Burmese ruby of "pigeon's blood" red, with no indications of heating. The ruby is framed by triangular and square cut diamonds in a strict geometric design from Cartier's early twentieth century platinum period. Rapaport reported a high estimate of HK$60m. The sale also includes a 21.05 ct Kashmir sapphire ring mounted by Cartier and a pair of Van Cleef & Arpels pearl earrings made in 1957 for the Duchess of Windsor.
Why Art Deco Cartier holds its place
In the early 1900s Cartier was among the first houses to work platinum on a large scale. The metal is strong enough to hold stones in very fine settings, which made the crisp lines of Art Deco possible. Signed Cartier pieces from the 1910s to the 1930s are sought after for three things together: the design, the quality of workmanship and the record of the house's archive.
What this means if you own Art Deco jewellery
With any Art Deco piece, the signature and its numbering, the metal, original fittings and the stones all matter. For rubies and sapphires, origin and the absence of heating are now central, which is why a modern laboratory report can change how a stone is seen. Never have a period jewel re-polished or re-set before a specialist has looked at it.
