At 5.03 carats, the rectangular-cut “Aurora Green” had been valued at $16 million to $20 million.
Although it sold at the lower end of that range, it set a “world auction record for a green diamond and world record price per carat for a green diamond”, Christie’s said.
The “fancy vivid green” diamond was among a variety of offerings at Christie’s “Magnificent Jewels” spring sale in Hong Kong.
