“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, 2013

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 three or four carats in size when polished. This diamond is almost four times larger than that size range.”

Jewels du Jour  posted on October 10, 2013 about this orange diamond:

" Weighing 14.82 carats, the Orange diamond is more than double the very few vivid orange diamonds that have been sold at auction in the past, all of which weighed less than 6 carats.

Pure orange diamonds, also called 'Fire diamonds' by famous gemologist Edwin Streeter in his book 'The Great Diamonds of the World' (1882), are exceptionally rare, making this particular stone the ultimate addition to any serious connoisseur's collection.

The diamond is expected to fetch between US$17 million to US$20 million."

"This store has a very pleasant environment and Jeff and Janet are both kind, wonderful people.

He uses scientific methods and tests rather than going solely by appearance as some jewelers will try to do, and his expertise is well respected.
