A selection of jewelry that belonged to members of the Mellon family will go up for auction at Sotheby’s in New York, including a sapphire and diamond Cartier necklace that could fetch up to $3.5 million.

The piece, with five emerald- and square emerald-cut Kashmir sapphires weighing between 4.44 and 10.01 carats, will feature in the Magnificent Jewels sale on June 8, Sotheby’s said last week. The necklace also contains round, baguette and square-cut diamonds.

The jewel was the property of Constance Prosser Mellon, wife of the grandson of Thomas Mellon, who founded T Mellon and Sons Bank. The family is widely known for its philanthropy, as well as for the development of Pittsburgh, Pennsylvania, investing in aluminum, steel and railroads. It also donated large sums to education, including to the University of Pittsburgh and to Carnegie Mellon University.

A Cartier ring containing an emerald-cut, 33.51-carat Burmese sapphire accented by baguette diamonds will also be on offer. Another Prosser Mellon piece, it has a presale price range of $1.5 million to $2.5 million.

Meanwhile, a Cartier ring features an emerald-cut, 12.35-carat Colombian emerald flanked by diamonds. It is estimated at $150,000 to $250,000.

Those three jewels will join several others from the Mellon family alongside the Eternal Pink, a cushion-cut, 10.57-carat, fancy-vivid-purplish-pink, internally flawless diamond that carries an estimate of more than $35 million. The Estrella de Fura, a 55.22-carat ruby that is the largest ever to appear at auction, will also star in the sale. It has a presale price of more than $30 million.

“The Magnificent Jewels sale…reflects the demand for spectacular jewels and colored gemstones, demonstrating the strength of the jewelry market amongst collectors around the world,” said Max Fawcett, head of jewelry for Christie’s in Geneva.

Some 11 lots realized more than $1 million, Christie’s noted. The auction featured jewels from Chaumet, Harry Winston, and other well-known designers and saw participation from bidders in 29 countries. Of those, 38% were located in the Americas, 34% in the Europe, Middle East and Africa region, and 28% in Asia Pacific.

A 126.76-carat diamond will go under the hammer at the upcoming Christie’s Magnificent Jewels auction in New York, with a price estimate of up to $15 million.

The pear brilliant-cut, D-color, internally flawless stone, known as the Light of Peace Diamond, will appear without a reserve price at the June 7 sale, Christie’s said Monday.

The diamond was previously the property of the Zale Corporation, which called it the Zale Light of Peace Diamond. The Zale family arranged showings of the diamond and used income from the ticket sales to establish a fund for peace-supporting missions, Christie’s noted. In a nod to the charitable efforts of the Zale family, the diamond’s current owners will donate a portion of its proceeds to the USA for UNHCR, the UN Refugee Agency.

A controversial three-part sale of jewelry belonging to late Austrian billionaire Heidi Horten achieved $202.2 million at Christie’s in Geneva, breaking the world auction record for a single collection.

The first portion of the auction, which took place live on May 8, contained 96 items and garnered $155.6 million, Christie’s said on Monday. The auction house sold 97% of items on offer at the event. The 152 lots in part two’s live auction on May 10 brought in a total of $42.4 million, with 99% of those goods finding buyers.

The final portion of the sale, which was held online from May 3 to May 15, fetched $4.2 million. Some 96% of the 154 items were purchased, Christie’s noted. Overall, the hammer dropped on 98% of goods on offer.

Christie’s faced backlash over the sale of Horten’s jewelry due to her husband’s ties to Nazi Germany. The World Federation of Diamond Bourses (WFDB) wrote a letter to the auction house opposing the sale and requesting that if it were to move forward, a major portion of the proceeds would be donated to charities supporting the welfare of Holocaust survivors, as well as commemoration and education.

Christie’s said it would donate a “significant portion” of its commission to Holocaust-related charities. However, all of the Heidi Horten estate’s proceeds from the auction are designated to benefit a foundation supporting medical research, child welfare, and access to the arts, in accordance with her wishes, the auction house said.

Here are the top sellers from the three portions of the auction:

Part I:

The Sunrise Ruby, a ring containing a cushion-shaped brilliant-cut, 25.59-carat ruby and diamonds by Cartier, fetched CHF 13.1 million ($14.6 million), missing its low estimate.

A Bulgari ring set with an emerald-cut, 6.99-carat, fancy-intense-pink, VVS1-clarity diamond brought in CHF 9.1 million ($10.2 million), more than double its upper presale price.

A necklace by Harry Winston featuring three strands of graduated natural pearls and a cushion-modified brilliant-cut, 11.15-carat, fancy-light-pink diamond went for CHF 6.5 million ($7.2 million), just over its bottom estimate.

Part II:

The Star of Africa, a necklace by Harry Winston bearing a pear-shaped, 54.95-carat ruby and pear, oval-shaped and round diamonds, garnered CHF 2.7 million ($3 million), nearly twice its upper price.

A necklace with a heart-modified brilliant-cut, 15.05-carat, fancy-orange-pink, VVS1-clarity diamond brought in CHF 2.5 million ($2.8 million), exceeding its upper estimate.

An emerald-cut, 47.58-carat, G-color, VS1-clarity diamond ring sold for CHF 1.9 million ($2.1 million), within its presale price range.

A watch by Piaget made with white gold and diamonds went for CHF 138,600 ($155,309), well above its CHF 38,000 ($42,579) high estimate.
