Worth Over $150 Million, This Epic Jewelry Collection Is Poised to Shatter Auction Records

Christie’s upcoming jewelry sale could be one of the biggest in history.

The two-part live auction, dubbed The World of Heidi Horten, comprises more than 700 pieces of high jewelry from the estate of the late European collector. Horten’s trove, which includes diamond rings, pearl necklaces, and dazzling bracelets, carries a staggering pre-sale estimate of more than $150 million. According to the auction house, it is the “largest and most valuable collection” to ever go under the gavel and could set a new auction record.

Growing up in Vienna, Austria in the 1940s, Horten learned to appreciate “objects of great beauty” from her father, who was an engraver. She later married German entrepreneur Helmut Horten and continued to hone her eye for jewelry and art. She educated herself over the years and only bought the best, as this collection shows.

Leading the sale is a Harry Winston necklace that has the legendary 90-carat Briolette of India diamond at the center. Originally sold by Cartier in 1909, the extravagant piece is expected to fetch an equally extravagant $10 million. Cartier’s “Sunrise” ruby-and-diamond ring of 25 carats is another standout and is estimated to fetch between $15 million and $20 million.
