For every 10,000 gem-quality diamonds found, only one possesses brilliant and coveted colour. Captivating and enigmatic, blue diamonds are considered the rarest of them all. A fabulous fluke of nature, a blue diamond is produced by the random presence of the atomic lattice-bound trace element boron within the stone’s carbon structure during its formation deep in the earth’s core.

Over centuries and up until today, blue diamond discoveries of any size are still sporadic and always astonishing occurrences. There are few numbers of exquisite blue diamonds offered at Replica Shoes ’s over the last five years including the Farnese Blue - a 6.16-carat fancy dark grey-blue diamond which was subsequently passed down through four of the most important royal families in Europe; the De Beers Millennium Jewel 4 – a rare and internally flawless 10.10-carat blue diamond that is the largest oval-shaped fancy vivid blue diamond ever to appear at auction; the Blue Moon of Josephine - sold in November 2015 at Replica Shoes ’s Geneva for over $4 million per carat – the world auction price-per-carat record for a diamond or gemstone; and most recently an exceptionally rare 5.17ct heart-shaped Fancy Vivid Blue diamond sold for over 10 million USD last year.

This Autumn we are delighted to bring in another beautiful 3.01 carat fancy vivid blue diamond. It is of a wonderfully clear celestial blue and presented in an emerald-cut - a very elegant and flattering cut for coloured diamonds which are favoured by many celebrities and collects ors. It was also found to be of Type IIb, a rare category which represents less than 0.5 % of all diamonds. With great beauty and rarity, this gem will certainly captivate collects ors of exceptional gemstones.

彩色鑽石之稀有程度無需贅述，而其中之最當屬藍色鑽石。作為最罕見的彩色鑽石之一，藍色鑽石是在離地面極端深度下形成的（約比大部分鑽石深四倍），其顏色或由硼元素所致，這些硼元素蕴含於遠古海洋層中，因構造板塊運動被帶到了地幔深處。

從古至今藍色鑽石的產量都極為稀有，一旦被發現無論尺寸大小都備受關注。在過去的五年裡，蘇富比拍場曾出現過少量的頂級藍色鑽石，包括來自歐洲皇室極具傳奇色彩的6.16克拉暗彩灰藍色鑽石『法納斯藍』The Farnese Blue；極為稀有10.10克拉內部無暇艷彩藍鑽『戴比爾斯千禧瑰寶第4號』The De Beers Millennium Jewel 4；2015年創世界拍賣記錄的『約瑟芬藍月』The Blue Moon of Josephine；以及2020年於香港蘇富比上拍的非常罕見5.17克拉心形艷彩藍鑽。

今次香港秋季拍賣蘇富比衷心呈現一顆3.01克拉祖母綠型切割艷彩藍鑽。色澤濃郁均勻，切割簡潔優美，是彩色鑽石中極為稀有也備受藏家喜愛的形狀。此顆天然藍鑽亦為Type IIb類鑽石，產量只佔所有天然鑽石的不到0.5%，絕對是頂級鑽石藏家及投資者首選。
