(IDEX Online News) – Another world record was broken for the sale of a colored diamond at auction, this time the 5.03-carat “Aurora Green,” which sold for $16.8 million at Christie’s Hong Kong Magnificent Jewel sale, according to a report on Forbes.com.

Hong Kong-based Chow Tai Fook purchased the rectangular-cut vivid fancy VS2 clarity green diamond, which is mounted on a gold ring surrounded by circular-cut pink diamonds. The $3.3 million per carat sale price more than doubled the previous record for a green diamond – the May sale of “The Ocean Dream” – a 5.5-carat fancy vivid blue-green diamond that sold for $8.6 million ($1.5 million per carat).

The Aurora Green was the highlight of the auction, although its sale price was toward the low end of the estimate. Other lots also broke records: Burmese oval-shaped ruby ear pendants of 10.02 and 9.09 carats by Etcetera sold for $11.6 million or $607,053 per carat – a world auction record for a pair of ruby earrings; and a Cartier Art Deco sapphire and diamond bracelet sold for $7.2 million – a world record for a bracelet.
