This is a partial list of the largest non-synthetic diamonds with a rough stone (uncut) weight of over 200 carats (40 grams).[1] The list is not intended to be complete – e.g., the Cullinan (formerly Premier) mine alone has produced 135 diamonds larger than 200 carats since mining commenced.[2] De Beers generally does not publish information relating to large diamond discoveries.
