附美國GIA證書（編號 6187293461，日期2017年4月10日）指方形艷彩黃色鑽石重5.29卡拉 ，VS1淨度，極優打磨及對稱。

        在頂級寶石的收藏家裡，庫裏南家族尤其熱衷於尋找最稀有耀眼的寶石。傳奇鑽石鉅賈之子R.V. 庫裏南曾請迪比爾斯董事皮耶·杜·維利耶將軍幫他尋找一些稀世鑽石。有一次在金伯利迪比爾斯礦場的回程火車上，乘客們正在討論最近遠征探險的成果，其中鑽石金礦大亨，迪比爾斯的股東歐內斯·奧本海姆爵士聲稱自己最近的收穫比杜·維利耶將軍更勝一籌。當奧本海姆爵士展示了自己所得的鑽石之後，維利耶將軍立刻與之達成購買協議，最終他與R.V. 庫裏南共同分享了這批鑽石收藏。

        上世紀初，托馬斯·庫裏南爵士在其鑽石礦中發現了迄今為止世界上最大的寶石級鑽石原石，重達3,106.75卡拉，而這顆以庫裏南爵士命名的鑽石原石以及他所創立的庫裏南鑽石世家由此聞名世界。庫裏南礦先後出產過幾顆不同切割及尺寸的鑽石，其中最大的一顆名為「庫裏南一號」，又稱「非洲之星」，被鑲嵌在英國皇家十字權杖上。第二大的鑽石名為「庫裏南二號」，又稱「非洲之星二號」，被鑲嵌在帝國皇冠之上。兩顆鑽石目前皆屬於英國皇室珠寶珍藏，剩下的幾顆鑽石則為英國女王私人珍藏。

        毫無疑問杜·維利耶將軍也注意到了這顆鑽石非同一般的顏色強度，不管是從正面還是側面都熠熠生輝。也正因如此將軍才急切地將其收入囊中。這顆被家族珍藏至今美麗稀有的鑽石毋庸置疑是收藏家錦上添花的新藏品。
