Catalogue Note

Brilliant Blues


Blue diamonds have the most marvelous and enchanting hues earning its stripes as one of the most coveted, valuable and extraordinary gemstones in the world. Since the 17th century, the value of coloured diamonds have been on a consistent incline, largely due to the recognition of its rarity in comparison to their near colourless counterparts along with the intriguing variations in hues and intensities which have been discovered. What makes these spectacular gemstones a true treasure is embodied in the combination of their magnificent hues and tones owing to the trace element of boron within the crystal structure and its brilliant cutting style.


The pair of round brilliant-cut fancy intense blue diamonds showcase impeccable craftsmanship through the diamond cutter’s ability to retain such a high level of saturation within a brilliant-cut. The round brilliant-cut is rarely employed on coloured diamonds due to the high wastage of diamond rough involved with creating the shape. A diamond rough of at least double its final carat weight is required to fashion a diamond into this highly lustrous and sought-after shape. Due to the rarity of rough coloured diamonds, most cutters would opt to maximize the use of the diamond rough and cut into more commonly seen shapes such as cushion-shapes or radiant-cuts which retain more rough material and produce higher carat weights.


The strength of a coloured diamond’s colour is evaluated based on its intensity level in accordance with the Gemological Institute of America’s eight level grading scale ranging from Faint Blue to Fancy Vivid Blue. Fancy Intense is the second highest acclamation that a coloured diamond can achieve, combined with the pure blue colour, absent of any modifying secondary hues, Lot 1753 is an exquisite example of its kind.


Reveling in the presence of one exquisite round brilliant-cut fancy intense blue diamond over 1 carat is a marvel in itself, but to be presented with two well-matched as a pair is beyond rare. Together with a pair of D Colour, Internally Flawless, Type IIa diamonds, the two stunning occurrences paired together are incredible to even the most discerning collectors.


輝煌的藍


藍色鑽石色彩美豔迷人、輝煌奪目,素有世界上最受推崇、貴重不凡的自然瑰寶之美譽。自十七世紀以來,彩色鑽石的價值有增無減,主要因為彩色鑽石比近乎無色的鑽石更罕有,現時亦已發現多種不同的顏色與濃度。藍色鑽石的鮮艷色彩由晶體結構裡的硼元素形成,結合巧奪天工的切割,令這些珍罕寶石成為不可多得的稀世奇珍。


這對圓形濃彩藍色鑽石採用明亮式切割後仍然保留高濃度成色,足見工匠技藝之純熟臻善。由於這種切割方式耗料極多,甚少用於彩色鑽石。如要打造出這種光彩絢爛、備受青睞的圓形外型,原石的重量需為成品至少兩倍或以上。正因為彩鑽的原石十分稀有,大部份工匠均會選用較常見的切割方式,如古墊形或方形切割,以求儘可能保留原石物料,令成品卡重更高,將原石的價值發揮到極致。


彩色鑽石的色彩濃度,根據美國寶石學院(GIA)所劃分的八大成色等級而評定,從微藍色至艷彩藍色不等。濃彩藍色為彩鑽評級中的第二高,拍品第1753號顏色純淨,不含任何人工雜色,堪稱藍色鑽石的精緻典範。


能夠見證逾1卡拉的圓形濃彩藍色鑽石誕生於世,本來已是一大奇蹟;兩顆款式相襯的藍鑽湊成一對,更是非同凡響。拍品配以一對D色內部無瑕Type IIa鑽石,兩者互相輝映,無疑是值得慧眼識珠的藏家追求的絕世珍寶。
