How we built this ranking and what to consider when choosing

Our methodology for ranking the largest diamonds in history is based on a comprehensive collection of public and verified information regarding the carat weight of these extraordinary gems. We focus on the documented magnitude of diamonds in their original rough state, as well as the most significant cut pieces.

  • Information regarding the carat weight of rough diamonds is prioritized, as this represents their original size upon discovery.
  • Both rough diamonds and the largest cut pieces resulting from them, such as the Cullinan I, also known as the Great Star of Africa, are considered.
  • A diamond's relevance for this ranking is based purely on its documented size, without considering factors like color, clarity, or cut, unless they directly affect the final weight of a cut piece.
  • Diamonds with significant weight that have been widely recognized in history and gemological records are included.
  • The primary criterion is the diamond's carat weight, either in its rough state or as a large cut piece. Documented magnitude is sought.
  • Only diamonds with a considerable carat weight that places them among the largest ever discovered or documented are included.
  • Preference is given to diamonds with a well-documented history of discovery and weight, such as the Cullinan, found in 1905.
  • Diamonds must be globally recognized for their exceptional size within the gemological community and historical records.
