幾千年來，祖母綠一直為世人所仰慕追求之寶石。它裝點過古埃及法老與羅馬大帝，16世紀的西班牙征服者在從拉丁美洲返回歐洲時，將其帶回歐洲。自此，祖母綠之地位達至頂點，並保持至今。

祖母綠在世界各地均有出土，成色最好的則來自哥倫比亞，尤其是木佐礦區。El Dorado祖母綠呈輕微藍綠色調，色彩生動活潑，經美國寶石學實驗室鑑定，指出產地為哥倫比亞，美國寶石學院與瑞士古柏林寶石鑑定所也得出相同鑑定結果。El Dorado是優質祖母綠的上乘典範。

其不僅顏色非凡，且未經淨度處理。大部分祖母綠出土後，都經油浸及樹脂處理，以降低自然雜質對外觀的影響。未經處理的祖母綠可謂少之又少。如同此枚El Dorado祖母綠一般肉眼觀察全無雜質的祖母綠更是珍罕稀有。

尺寸如此之大、色彩及淨度如此優秀、未經任何處理的祖母綠真可謂是稀世奇石。
