如果要比較彩鑽的稀珍程度，紅鑽要數第一，而排在第二位的則是綠鑽。鑽石之所以會呈現綠色在是因為原石在地底深層經歷了數百年的天然輻射，藏身於鈾的化合物中或滲濾的地下水中，因而改變了其結構以至光譜的吸收。大部份自然幅射所得的綠鑽的顏色都侷限在最表層，一經打磨，顏色甚至會全然消失。事實上只有一小部分原石經歷到長時期持續的輻射，顏色分佈平均，通體發綠。當中又只有極少的綠鑽顏色正綠，不帶任何藍、灰或黃的副色；此重達4.90卡拉的心形綠鑽正正就是如此鳳毛麟角，一物難求。
史上最有名的綠鑽無疑是「德累斯頓綠鑽」──一顆重41.10卡拉、呈藍綠色的梨形綠色鑽石。傳說此巨鑽產自印度，於1741年的萊比錫博覽會上由荷蘭商人Delles售予弗雷德里克·奧古斯特二世，即當時的波蘭國王。聞說其時在歐洲市場上並沒有出現過類似的寶石，此綠鑽當屬第一顆。
在過往三十年來，出現在拍場上的綠鑽為數不多，而且大部分都帶有藍或黃的副色。這顆濃彩綠鑽色澤純正，切割成線條完美的心形，加上重達4.90卡拉，在天然綠鑽中絕對是極具份量的代表。
