Christie's auction house says an egg-sized white diamond known as ``The Rock'' has sold for the equivalent of 28.2-million dollars Canadian.
The 228-carat pear-shaped stone is billed as the largest of its kind to go up for auction.
The 228-carat pear-shaped stone, with its platinum pendant mounting, has a gross weight 61.3 grams (2.2 ounces) and dimensions of 5.4 centimeters by 3.1 centimeters (2.1 inches by 1.2 inches), making it about the size of a medium hen's egg.
Also sold was the ``Red Cross'' diamond, a more than 205-carat fancy yellow stone, which fetched nearly 18.5-million dollars.
Both went to unspecified private buyers.
