The largest purple diamond auction ever sold for 24,393,000 Swiss francs (26,700,871

US dollars) in Geneva, Switzerland.

At the Sotheby’s auction on Tuesday, the purple-pink diamond named “Spirit of the Rose” was sold to an anonymous buyer and bid on the phone. It weighs 14.8 carats but was cut from a larger rough diamond weighing 27.8 carats, which was discovered in 2017 in Yakutia in northeastern Russia.

It is said that this unprocessed diamond is the largest pink crystal in the history of Russia, named “Nijinks” after the legendary Russian-Polish ballet dancer Vaslav Nijinsky (Vaslav Nijinsky). After the last time the Rose Gold Ballet (Nijinsky) performed on stage, the diamond’s name was named “Spirit of the Rose”.

It took a year for the Russian master cutter to form the final diamond, making it oval to ensure the maximum size.

Pink diamonds were first discovered in India in the 17th century. Its color is believed to be the result of “lattice” distortion or the arrangement of its atoms. According to the explanation on the Sotheby’s website, this was “caused by intense heat and tremendous pressure after the stone was formed.”

The auction house explained: “This distortion moves many carbon atoms away from their normal positions and changes the quality of the light reflected by the diamond-causing us to observe that the diamond is pink.”

Pink diamonds are different from other colored diamonds because there are no chemical trace elements in the formation process. For example, the presence of nitrogen forms yellow diamonds, while boron forms blue diamonds.

It is said that only 1% of pink diamonds are larger than 10 carats, and only 4% of diamonds are classified as “brilliant and vivid.”

The “CTF Pink Star” weighing 59.6 carats holds the current record for the price of pink diamonds at auction, at US$71.2 million, and was sold in Hong Kong in April 2017.

The “big watch” shown to French merchants and adventurers in the 17th century is believed to be the largest pink diamond ever recorded, weighing 200 carats.
