In gemmology the term paragon refers to any flawless diamond with a mass of at least 100 carats.
Currently the largest flawless natural diamond (as opposed to synthetic diamond) in the world is known as The Paragon, a D-color gem weighing 137.82 carats (27.564 g), [1] and the tenth largest natural white diamond in the world.[ citation needed ] The gem was mined in Brazil and attracted attention for being an exceptional white, flawless stone of great size. [2] The Mayfair-based jeweller Graff Diamonds [3] acquired the stone in Antwerp, cut it into an unusual seven-sided kite shield configuration, and set it in a necklace which separates to both necklace and bracelet lengths. Apart from the main stone, this necklace also contains rare pink, blue, and yellow diamonds, making a total mass of 190.27 carats (38.054 g). [4] The necklace has associations with the end of the millennium and was worn by model Naomi Campbell at a diamond gala held by De Beers and Versace at Syon House in 1999. [5]
