HONG KONG'S MOST sophisticated and understated socialites never miss the fine art sales. Their devotion was rewarded at Christie's auctions at the Marriott, with action aplenty in the shape of a world record bid, the $6.64 million paid for The Three Riders by Xu Beihong. This heady sum almost doubled the 1997 previous best for a Chinese oil painting of $3.87 million. Charles Yang accompanied his mother Lucy, who was glowing in a delightfully retro Leonard outfit. Since Asia's art cognoscenti are among the antique and art world's big spenders, specialists in all fields make the trip to touch base with their SAR clients. Renowned jewellery specialist Rahul Kadakia flew in from Geneva to show this season's highlights - including a 10-carat Burmese ruby ring - to Michelle Ong Cheung, jeweller and co-chair of the ladies' committee of the Hong Kong Philharmonic. Well-known art investor Roger King, of discount cosmetics chain SaSa, chatted with Anthony Lin of Christie's Asia. Photographers were snap-happy for watch specialist and former actress Mary Lee, daughter of the late movie director Lee Hong-cheung.
