The largest known fancy intense pink diamond went unsold at Sotheby’s on Wednesday amid jitters in the final round of the Geneva fall auction season that contrast with the stellar price won by a painting by Leonardo da Vinci.

Sotheby’s had estimated the value of the Raj Pink, a 37-carat stone, as high as $30 million. Other lots unsold in the auction included a vivid blue diamond ring estimated at as much as $18 million and two yellow diamonds worth as much as $14 million. The blue diamond was sold privately immediately after the sale, Sotheby’s said.
