But at least one offer has been made on the stone for $40 million. However, CEO William Lamb believes the diamond could be worth "north of $60 million."

"The significance of the recovery of a gem quality stone larger than 1,000 carats, the largest for more than a century and the continued recovery of high quality stones...cannot be overstated," Lamb said in a Nov. 18 statement.
