The earrings were sold as separate lots. After protracted bidding, the flawless and vivid "The Apollo Blue" fetched US$42.087-million and the equally intensely luminescent "The Artemis Pink" went for US$15.33-million, buyers premium included.
The earrings, named after Greek gods, had respectively been valued at between US$38-million and US$50-million and US$12.5-million and US$18-million.
The 14.54-carat "Apollo Blue" is the largest gemstone in its category ever to be auctioned and has been cut and polished to a pear shape.
The 16-carat "Artemis Pink" is near identical in shape. It is also one of the world's most "chemically pure" diamonds, according to the Gemological Institute of America, which experts say gives the stone such a high degree of transparency.
