The Incomparable Diamond


With yellow diamonds increasing in value astronomically, we thought we would take a look at one of the most famous yellow diamonds ever recovered, the Incomparable Diamond.

Weighing in at 890 carats in it’s rough form, the stone was originally found in the early 1980s in the town of Mbuji Maya in the Democratic Republic of Congo.   Ironically, the diamond was found among the rubble from a diamond mine that had been rejected as not containing anything of value.

The yellow stone ended up in the hands of De Beers who gave it to famed gem cutter Leo Wins to cut down into smaller diamonds.  The final result was that the massive gem was cut down into one large diamond weighing 407.48 carats and 14 smaller diamonds ranging from 1.33 carats to 15.66 carats.



The largest diamond, now owned by Mouawad Jewelry, is considered the largest Internally Flawless diamond ever graded by the Gemological Institute of America.  The stone is the centrepiece of L’Incomparable diamond necklace which also features 35 round diamonds, 27 pear-shaped diamonds, nine heart-shaped diamonds, five emerald-cut diamonds, five cushion diamonds, four oval diamonds, three Asscher-cut diamonds and two radiant diamonds. The total diamond carat weight for the piece is 637 carats.   When first exhibited in 2013, the necklace set the Guinness World Record as the most expensive necklace with a value of $55 million.
