拍品資料及來源

多數彩色鑽石的色澤來自其包含的雜質,這些雜質在晶體形成時意外混入其中,整個過程發生在距離地表數百英里的深處。鑽石主要由純碳組成,其他元素的入侵導致其顏色轉變,如氮元素會令其變成黃色,硼元素則為藍色。粉紅色卻可能由晶體結構扭曲而導致,目前科學尚未得出令人信服的解釋。

粉紅色彩鑽非常珍罕,大顆的更是鳳毛麟角。根據美國寶石學會(GIA),每年全球粉紅色至紅色鑽石的開採量一手可握。是次拍賣的這顆鑽石無與倫比,呈現出非常明亮、令人陶醉的濃彩粉紅色。此鑽石中可見不同的顏色濃度;其光輝、色彩及尺寸均為舉世罕見。

目前有記錄以來的鑽石或寶石最高拍賣價格由「粉紅之星」保持,其為世上珍貴的天然寶物,及後更名為「周大福粉紅之星」。此顆瑰麗鮮彩粉紅色鑽石重59.60卡拉,於2017年4月假香港蘇富比以7120萬美元成交。

目前濃彩粉紅色鑽石的每卡拉價格紀錄則由「格拉芙粉紅鑽」保持,其重24.78卡拉,於2010年11月假日內瓦蘇富比以4620萬美元成交。

切割及打磨

此鑽石於2015年在南非開採出土,開始切割前對原石的研究持續了一年有餘,後交予一位切割大師。

「細心觀察這顆粉紅鑽石的最終形態--37.30卡拉光華璀璨的古墊形瑰寶--我們很容易就忘記它從原石蛻變成打磨成石的過程。」「儘管大自然賜予這顆寶石罕見的顏色及淨度,切割大師功不可沒,是其好好利用這些特徵,令它最美的一面毫無保留地呈現人前。」

「儘管在打磨鑽石時會考慮到它將會從一個特定角度受人觀察,也俗稱『面色』,但是我們必須把所有立體結構都考慮其中,才能讓特定的一面盡善盡美。」「原石形狀通常決定了鑽石的最終形狀,切割卻是一門平衡各方的藝術,也是一個有機的過程。切割師在保留最大重量的同時,也必須讓鑽石取得最好的色彩與淨度。」

「GIA經年的研究發現古墊形圓形切割最能帶出鑽石呈現的色澤濃度。」「古墊形稍微彎曲的側面及圓角提供了視覺上的平衡感,柔和了現今鑽石硬淨尖角的幾何琢面。」「三角及風箏形刻面的切割工藝繁複,在光線下折射出璀璨光華,讓鑽石充滿生機,更為迷人。」「切割師為追求彩色鑽石最亮麗的效果,有時會稍稍調整切割風格。」

顏色

「如『The Raj Pink』一般呈現濃艷的原生粉紅色在鑽石中非常罕見,尤其是它的重量如此驚人:鑽石越大,就越難呈現出飽和的深色。」
