Two years ago a diamond was unearthed in Botswana that weighed 1758 carats...that's almost ten times that of the crown Jewell Kooh-i-noor that was originally surrendered to Queen Victoria by India.
They are still looking at it to determine best way/practice to maximize its value...the Crown Jewell is worth approx. 541 million USD...It's like our molecule...lots of sparkle...lots of eyeballs...just need to know how to partition it.
