This per-carat price beat the record held by a 12.03-carat blue diamond – The Blue Moon of Josephine – which notched $4 million per carat in 2015. 

"The flawless clarity of the [Williamson Pink Star] was matched by the flawless auctioneering and our team’s execution – the Williamson Pink Star now takes its place in the pantheon of world record-breaking gemstones of the rarest kind," Wenhao Yu, chairman of jewelry and watches at Sotheby’s Asia, said in a statement.

"Ultimately, what we have witnessed in the room reflects the appetite for rare and impeccable gemstones amongst global collectors," Yu continued.

The Williamson Pink Star reportedly came from a 32-carat rock that was sourced from the Williamson Diamond Mine in Tanzania.
