The 14.93-carat fancy vivid pink diamond will lead the auction house’s Magnificent Jewels sale on Nov. 28.

Hong Kong--Christie’s Hong Kong is readying itself to sell the most expensive jewel it has ever offered.
Later this month, a 14.93-carat Type IIa fancy vivid pink diamond of VVS1 clarity will be up for sale and it is expected to garner between $28 million and $42 million.
“The Pink Promise” will lead the Magnificent Jewels sale Nov. 28, a sale that will feature more than 290 lots, including a number of colored diamonds, exceptional gemstones and jadeites.
Another highlight is a second pink stone--an 8.80-carat VVS1 Type IIa fancy intense pink diamond that could sell for as much as $12 million.
There also will be an 8.17-carat Burmese ruby ring (below) that is expected to garner between $5.8 million and $8 million.

Meanwhile, a necklace featuring jadeite beads--each between 14.7 and 15.9 mm--could garner up to $10 million, while another jadeite pendant has a pre-sale estimate of between $3.5 million and $4.8 million.
A 28.04-carat Sri Lankan padparadscha sapphire and diamond ring also will hit the block. Christie’s estimates it will sell in the range of $2 million to $3.2 million.
The Magnificent Jewels sale also will put on offer a range of important signed pieces from renowned jeweler Wallace Chan.
The “Wallace Chan: The Beginning of a Genius” collection was created by the jeweler and artist during “his most innovative period of self-discovery in the late 20th century,” Christie’s said.
Trained as a sculptor from an early age, Chan’s pieces reference traditional Chinese icons and incorporate elements of nature as he explores jewelry’s sculptural limits.
He continues to experiment with different methods and materials to bring his vision to life, while finding a way for his pieces to embody his design philosophy of harmonizing the symbols of heaven, earth and humanity.
The auction will feature a collection of his works spanning reinterpreted traditional icons, like Chinese zodiac signs made from carved jadeite, to contemporary designs, like butterflies and flowers with vibrant colored gems.
