The diamond bling fetched a whopping $749,000 earlier today!
"It bounced between two phone bidders and two bidders in the back of the room," the Christie's spokesperson tells E! News. "Good participation all around. It was the last item in the morning session."
The final sale price far exceeded the presale estimate of between $300,000 and $500,000.
"Kris is very pleased with the final result," Humphries' rep told E! News of the sale, which a source tells us came through Christie's Geneva office. The rep adds that Humphries hasn't decided on which charity to donate the proceeds to, but that it's a "top priority" for the 28-year-old basketballer.
Last week, Humphries' rep confirmed to E! News that the sports star planned on auctioning off the ring.
"The ring is indeed Kris' property that he received through his marriage dissolution," the rep said in a statement. "He has long-since moved on and is very much looking forward to a successful auction at Christie's on Tuesday, and of course to returning to the court this upcoming NBA season as a Boston Celtic."
