A fancy colored diamond, known as “The Indian Blue,” is the top lot of the upcoming Sotheby’s New York Magnificent Jewels sale on December 10. The 7.55-carat fancy deep grayish blue diamond with SI2 clarity is mounted on a ring flanked by two shield-shaped diamonds. Its estimate is $6 – $8 million.

More than 200 jewels with estimates ranging from $5,000 to $8 million will be on offer at Sotheby’s York Avenue galleries. It includes a number of pieces with notable provenance, including jewels owned by Mary Duncan Sanford, Charlotte Ford and Princess Natalie Paley; as well as fancy colored diamonds, signed jewels and even creations by the iconic surrealist artist, Salvador Dalí.

The number two lot of the sale is a flexible bracelet called “The Majestic Pink” made of 204 radiant and marquise-shaped diamonds of various fancy pink and red diamonds weighing approximately 43.34 carats. The piece was created by New York-based jewelers Carvin French. All of the fancy colored diamonds are from the Argyle mine in Australia, the source of more than 90% of the world’s pink diamonds. Argyle pink diamonds are already prized for their rarity and beauty but the value of these diamonds are expected to skyrocket beyond already record-breaking prices because the mine is scheduled to close in 2020. Originality listed as “price upon request,” Sotheby’s said in a statement that its estimate is in the vicinity of $3 million.
