The 6.21-carat fancy vivid pink diamond is expected to return $USD15 million ($AUD22.78 million) at the 13 May auction.
The event will be hosted at the Hotel President Geneva for the first time. More than 100 specially curated pieces from designers, including Cartier, Suzanne Belperron, and Van Cleef & Arpels, will also be displayed.
Another notable entry in the auction is the Amazon Queen, a 280-carat Colombian emerald from a private collection.
The emerald will enter the sale with a presale estimate of $USD1.5 million ($AUD2.28 million).
A 27.27-carat fancy vivid yellow diamond ring is also expected to impress bidders. It commands a presale estimate of $USD1.1 million ($AUD1.67 million).
Before the auction, Phillips will host exhibitions of the gemstones and jewellery in New York, London, Taipei, Taiwan, and Singapore.
This auction comes after a fancy colour yellow diamond ring was the star of the show at a Phillips auction in Hong Kong, returning $USD1.1 million ($AUD1.69 million).
