There was buzz about a month ago that the hoops star was planning on selling the 16-karat sparkler to the highest bidder at Christie's in New York.
Earlier today, Humphries rep finally confirmed the rumors.
"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."
