“The Orange,” a 14.82 ct. gem considered the largest fancy vivid orange diamond in the world, will lead Christie’s Magnificent Jewels auction in Geneva on Nov. 12.
The stone carries an estimated sale price of $17 million to $20 million.
The Christie’s statement notes that orange diamonds—also called “fire diamonds”—are exceedingly rare; the only other fancy vivid orange diamond sold at auction weighed 6 cts.
The auction house’s statement also includes a note from the GIA Laboratory: “In the Laboratory’s experience, strongly colored diamonds in the orange hue range rarely exceed 3 or 4 carats in size when polished. This diamond is almost four times larger than that size range.”
Other highlights of the upcoming Christie’s auction include:
- An exceptional ruby and colored diamond ring, set with a 5.09 ct. oval-shaped Burmese ruby. It carries a $1.6 million to $2.8 million estimated price tag.
- An Art Deco emerald and diamond necklace by Van Cleef & Arpels, formerly part of the collection of Egypt’s Princess Faiza, daughter of King Fouad. Its estimated price is $2.7 million to $3.7 million.
- A seven-strand natural pearl and diamond necklace made of 614 natural saltwater pearls. It is expected to sell for $3 million to $4.5 million.
