Egg-sized diamond fetches over $21M with fees at Geneva sale
Christie’s says “The Rock,” an egg-sized white diamond billed as the largest of its kind to go up for auction, sold Wednesday for more than 21.6 million Swiss francs ($21.75 million), including fees — though at the low end of the expected range. The 228-carat pear-shaped G-Color stone, with its platinum pendant mounting, has a gross weight of 61.3 grams 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.
