Western Star Auctions of Kelowna, British Columbia, said there were no offers for the 57,500-carat green stone, which weighs 25 pounds, after a memo was given to bidders at the Saturday auction explaining that co-owner Regan Reaney had been arrested Friday on charges unrelated to the emerald, the Kelowna Daily Courier reported Monday.

Mike Odenbach, owner of Western Star Auctions, told the Daily Courier the future of the emerald is up to the consignors. "Whatever they choose to do with it is up to them. I hope somehow [it] finds a spot in Kelowna."
