It said in a statement that the diamond will go on sale at the next tender which is scheduled to take place in September 2019. 
"The Liqhobong mine has become known for its fancy yellow stones but this one is the largest we've recovered so far and is therefore quite special,” said company chief executive Paul Bosma.
“Although certain segments of the diamond market are currently struggling, the demand for unique natural stones remains positive."
Firestone commenced commercial production at Liqhobong in July 2017.
