Quig Bruning, head of Sotheby's jewelry department in New York, emphasized the rarity of 100-carat diamonds, stating, "One hundred-carat diamonds as a rule are exceedingly rare. One hundred-carat D flawless are even more rare." While Sotheby's does not provide an official estimate, comparable diamonds have historically sold for amounts ranging from $11 million to $30 million.
The diamond, dubbed "the size of a lollipop" by Sotheby's, will be auctioned in Hong Kong on October 5, with online bidding starting earlier. If an online bidder secures the purchase, it could surpass the current record for the most expensive jewelry ever sold online, held by a pair of fancy blue and pink diamond earrings that sold for $6 million in 2016.
The 102-carat stone was crafted from a 271-carat rough diamond discovered in Ontario's Victor Mine in 2018. Over the course of a year, it was meticulously cut and polished by Diacore to enhance its "best brilliance, fire, and scintillation." Classified as a "Type IIa" diamond, it belongs to an elite subgroup known for being the most chemically pure with the highest level of transparency.
