WORLD’S LARGEST ORANGE DIAMOND EXPECTED TO REACH $20 MILLION
Weighing in at 14.82 carats, the pear shaped vivid orange diamond nicknamed ‘The Orange’ is an extraordinarily rare and one-of-a kind piece that is expected to reach $20 million at a Christie’s auction in Geneva next month on November 12th at the Four Seasons Hotel des Bergues.
The sheer magnitude and purity of the diamond breaks a world record as the last recorded vivid orange diamond (the Pumpkin Diamond) to go on sale at auction weighed in at less than 6 carats and was sold in 1997 for $1.3 million. Today, the Pumkim Diamond is worth an estimated $3 million.
The gemological Institute that graded ‘The Orange’ issued its report and stated that: “Strongly colored diamonds in the orange hue range rarely exceed three or four carats in size when polished. The diamond is almost four times larger than that size range. In GIA’s colored diamond grading system, as the color appearance of strongly colored diamonds transitions from orangy yellow to orange the occurrence becomes progressively more rare-that is-the less yellow present the more rarely they occur.”
While a vast amount of diamonds contain some nitrogen, in orange diamonds the nitrogen atoms absorb light in the blue and yellow region of the spectrum producing an orange color. The more intense this color is, the more value it is worth.
