It weighs 14.54 carats, compared with the 14.62 carat of the Oppenheimer Blue which was sold for CHF 57M including premium by Christie's on May 18, 2016.
The Blue Moon that became after its sale the Blue Moon of Josephine is also a Type IIb. Sold for CHF 49M including premium by Sotheby's on November 11, 2015, this diamond weighing 12.03 carats owes its culminating value at US $ 4M per carat to an absolute purity generating a sensational effect of phosphorescence after exposure to ultraviolet rays.
The diamond that comes in the next sale is pear shaped. Someone had the idea to choose a pink diamond of comparable cut and size. The two gems hanging each to a suite of two white diamonds thus constitutes temporarily the most sumptuous pair of earrings of all time. They are named Apollo and Artemis by reference to the beautiful twins of Greek mythology.
Nevertheless this pair will be divided. Artemis is estimated CHF 12.5M, lot 378. It is a Fancy intense pink Type IIa and VVS2 clarity weighing 16.00 carats. The market generally prefers a Fancy vivid pink. Of the same Type, clarity and form, a Fancy vivid pink weighing 15.38 carats was sold for CHF 31M including premium by Sotheby's on May 17, 2016.
