A Big Pink and a Big Blue Diamond Fetched Big Bucks At Christie’s

Two fancy colored diamonds were the top sellers at Christie’s New York Magnificent Jewels sale Tuesday. Meanwhile, the diamond engagement ring that Kris Humphries gave to Kim Kardashian at the same sale made lots of noise but ended up only having the 12th highest sale price at $749,000.

The top lots among the 389 offered were:

* An 8.77-carat rectangular-cut fancy intense pink VVS1 diamond that sold for more than $6.3 million, or $721,200 per carat (top photo). The buyer was Moussaieff Jewellers, a luxury retail jeweler with stores in London and Geneva.

* A 3.81-carat rectangular-cut fancy vivid blue VS1 diamond that sold for nearly $4 million, or more than $1 million per carat (pictured above). The buyer requested anonymity.

The other top lots are as follows:

* A 25.30-carat rectangular-cut D color VVS1 diamond that sold for more than $3.1 million.

* An 18.28-carat cushion-cut D color VVS2 diamond that sold for more than $2 million.

* A 15.88-carat cushion-cut Kashmir sapphire that sold for more than $1.8 million.

* A 10.75-carat rectangular-cut D color internally flawless diamond that sold for nearly $1.4 million.

The auction at Christie’s Rockefeller Center headquarters took in more than $46.6 million with 75 percent of the items sold by lot and 85 percent sold by value.
