A blue diamond weighing 11.16 carats sold for $25.2 million on Tuesday, becoming the most valuable jewel at this year’s Geneva auctions, according to Sotheby’s.

The Bulgari Laguna Blu, a pear-shaped, fancy-vivid-blue stone, surpassed its $25 million high presale estimate after a four-minute bidding battle between several buyers, Sotheby’s noted. It was the lead item in the Magnificent Jewels and Noble Jewels sale, which realized $85.4 million — Sotheby’s highest total for that auction in five years.

“The sale of the Laguna Blu tops the remarkable performance of our Magnificent Jewels and Noble Jewels sale that saw exceptional colored gemstones, in particular emeralds and yellow diamonds, punch through their high estimates,” said Olivier Wagner, head of jewelry for Sotheby’s Geneva.

These are the other lots rounding out the top 10:

This ring is set with a cut-cornered rectangular modified brilliant-cut, 21.94-carat, fancy-intense-pink diamond bracketed by half-moon fancy-deep-greyish-blue diamonds weighing 0.51 and 0.46 carats. It sold for $11.8 million, near the top of its presale estimate.
A ring with a round-cornered rectangular modified brilliant-cut, 5.01-carat, fancy-vivid-purplish-pink diamond surrounded by white diamonds garnered $6.3 million, just missing its lower price tag.
A pendant bearing a cushion-shaped, 132.83-carat sapphire and diamonds brought in $4.4 million, exceeding its high estimate.
Sotheby’s sold this Harry Winston ring featuring a cushion modified brilliant-cut, 51.52-carat, F-color, internally flawless diamond for $2.1 million, within its presale range.
This step-cut, 18.78-carat, D-color, VVS2-clarity diamond ring by Bulgari went for $1.7 million, soaring over its upper estimate.
A step-cut, 11.57-carat, fancy-vivid-yellow diamond ring brought in $1.3 million, more than doubling its $613,242 upper target price.
Nearly quadrupling its $306,543 upper estimate, this necklace featuring two rows of graduated natural pearls with a diamond clasp, from the collection of a princess, scored $1.2 million at the sale.
A Harry Winston necklace from the collection of a princess brought in $1.1 million. The price for the piece, which is set with an oval, 37.92-carat Padparadscha sapphire, surpassed its high estimate.
This marquise-shaped, 15.05-carat, D-color, VVS1-clarity diamond ring sold for $1.1 million, more than three times its upper price.
