A Graff ring with a bubblegum pink diamond sold for a record HK$83.5 million ($10.8 million) at a successful Christie's Hong Kong auction fueled by Chinese buying. The potentially flawless stone broke the per-carat record for a diamond. While on the other side of the globe, a re-discovered trove of Fabergé, which belonged to the Romanov family and lay "unknown for 91 years," tallied £7 million, at Sotheby's in London.
