The square emerald-cut, 41.36-carat, D-color, VVS1-clarity diamond, which is potentially internally flawless, is one of the top items set to go under the hammer at the November 8 Magnificent Jewels auction, Christie’s said last week.

Several other diamonds will also take center stage, including an unmounted modified shield brilliant-cut, 101.27-carat, F-color, VVS1-clarity diamond. That stone carries a high estimate of CHF 3.5 million ($3.5 million). A pair of Art Deco modified pear brilliant-cut diamond earrings by designer Henri Picq will also be up for sale. The set, featuring one 15.39-carat, D-color, VS1-clarity diamond and one 14.85-carat, D-color, VS2-clarity stone, has an upper price tag of CHF 2.5 million ($2.5 million).

Other notable items include a cushion brilliant-cut, 20.08-carat, F-color, flawless diamond ring, estimated at up to CHF 1.5 million ($1.5 million). A pear brilliant-cut, 14.19-carat, D-color, internally flawless diamond ring has a high price of CHF 1.2 million ($1.2 million).

Those stones will join the Fortune Pink, a pear-shaped, 18.18-carat, fancy-vivid-pink diamond. The gem, which Christie’s claims is the largest of its cut and color to be offered at auction, is expected to bring in up to CHF 35 million ($35.1 million). The sale will also showcase royal jewels from the Bourbon Parma family and from the Thurn and Taxis family.
