List of largest rough diamonds


This is a partial list of the largest non-synthetic diamonds with a rough stone weight of over 200 carats. The list is not intended to be complete—e.g., the Cullinan mine alone has produced 135 diamonds larger than 200 carats since mining commenced. De Beers generally does not publish information relating to large diamond discoveries.
