Take a Look at the 228-Carat Diamond Set to Fetch $20-$30M at Auction
Christie’s Geneva will offer “The Rock” at the Magnificent Jewels sale in May.

The auction house will present the aptly titled “The Rock,” a 228.31-carat pear-shaped diamond, seen in the video below.
The GIA has issued a letter that accompanies the stone, stating it is the largest existing D-Z color pear-shaped diamond the institute has ever graded.
The stone is G-color, VS1 clarity. It is expected to sell for between $20 million and $30 million at the Magnificent Jewels sale on May 11.
It’s currently on a world tour prior to the sale, starting in Dubai through March 20, then heading to Taipei, and finally New York City April 29-May 1. It will be on view in Geneva at the Four Seasons Hotel des Bergues May 6-11.
Christies’s International Head of Jewelry Rahul Kadakia said in a statement: “The Rock will join the very best of legendary gemstones which have passed through Christie’s global salerooms since 1766. The market for diamonds is particularly vibrant, and we are confident that this sensational gemstone will capture the attention of collectors across the globe this spring season.”

The Rock beats Christie’s top five largest white diamonds ever sold by quite a bit.
The stone that holds Christie’s auction record for the most expensive colorless diamond is the De Grisogono 163.41-carat diamond offered in 2017. It sold for nearly $34 million, despite some industry controversy over De Grisogono’s leadership. (The company was later accused of being a money laundering front and later filed for bankruptcy.)
The second most expensive white diamond Christie’s has sold was the “Winston Legacy” in 2013. The 101.73-carat diamond earned close to $27 million.
The No. 3 diamond was the 76.02-carat “Archduke of Joseph Diamond” in 2012, which earned $21.5 million, followed by the “La Legende” necklace by Boehmer et Bassenge at No. 4. The 92.15-carat diamond fetched $15 million in 2017.
But the most expensive white diamond to ever sell at any auction house wasn’t the largest; instead, it boasted an incredible provenance.
In 2018, Sotheby’s sold the diamond and pearl pendant that originally belonged to Marie Antoinette in its “Royal Jewels from the Bourbon-Parma Family” auction. It fetched a cool $36 million.
While Christie’s “The Rock” is the largest colorless diamond to appear at auction, the largest fancy color diamond was the 555.55-carat black diamond called “The Enigma.”
It sold this year at Sotheby’s for $4.3 million.
