A fancy orangy pink diamond weighing more than 30 carats will make its auction debut this December at a Sotheby’s sale in Abu Dhabi, the capital of the United Arab Emirates.

The stone, named “The Desert Rose,” is the largest fancy vivid orangy pink diamond ever graded, according to the auction house. It is estimated to sell for $5 million to $7 million.

Weighing 31.68 carats, the pear-shaped diamond has a “sunset-like” blend of pink and orange, Sotheby’s said.

The auction house introduced the stone at its “Beyond: The World’s Rarest Diamonds” exhibition, which it held in collaboration with the Abu Dhabi Investment Office (ADIO) this past April. 

It was the auction house’s first public exhibition in Abu Dhabi since 2009, signaling Sotheby’s desire to connect with the ultra-rich residents of the Middle East, and the region’s emergence as a global hub for luxury.
