图6 Shown here are the replicas of the major Cullinan diamonds with a one carat (ct) diamond (bottom left) for scale. They were cut from the 3,106 ct Cullinan diamond crystal found in South Africa in 1905. This record-setting crystal produced nine major gems and 96 smaller diamonds. The two largest, the 530.20 ct Cullinan I and the 317.40 ct Cullinan II, are part of the British Crown Jewels, while the rest of the major diamonds (Cullinan III-IX) were privately owned by Queen Elizabeth II. In 2023, the Queen Consort Camilla will wear Queen Mary's Crown, which features 2,200 diamonds and was worn by Queen Mary when she took part in the coronation alongside her husband, King George V, in 1911. As a tribute to the late Queen Elizabeth, the headpiece will be reset with the Cullinan III, IV and V diamonds, which are part of the famous Cullinan diamond, the largest ever found. The jewels were a part of the late monarch's personal jewelry collection and were frequently worn as brooches. Image: GIA
【机器翻译】这里显示的是库里南主要钻石的复制品，左下角有一克拉（ct）钻石。它们是从1905年在南非发现的3106克拉库利南钻石晶体中切割出来的。这颗创纪录的水晶生产了9颗主要宝石和96颗较小的钻石。最大的两颗，530.20克拉的库利南一号和317.40克拉的库里南二号，是英国王室珠宝的一部分，而其余的主要钻石（库利南III-IX）则由伊丽莎白二世女王私人拥有。2023年，卡米拉王后将戴上玛丽女王的皇冠，上面有2200颗钻石，是玛丽女王在1911年与丈夫乔治五世国王一起参加加冕礼时戴的。作为对已故伊丽莎白女王的致敬，该头饰将重新镶嵌库利南III、IV和V钻石，这些钻石是有史以来发现的最大的著名库利南钻石的一部分。这些珠宝是已故君主个人珠宝收藏的一部分，经常作为胸针佩戴。图片：GIA
