At 530.20 Carats, the Cullinan I or Star of Africa is the largest cut diamond in the world. Pear shaped, with 74 facets, it is set in the Royal Scepter, part of the Crown Jewels in the Tower of London. It was cut from the 3,106-carat Cullinan, the largest diamond crystal ever found. Legend suggests that it may have been part of a much larger rough diamond. Our Cullinan Collection is inspired by gems that could have been cut from this missing piece of priceless history. We have used only the finest solid 925 Sterling Silver lavishly plated in 18k yellow gold and set with our brilliant round cut Diamondeau? - flawless simulated diamond plus matching pear cut Diamondeau? - flawless simulated diamond.
