Diamonds, despite it being one of the most historically sophisticated gems in relation to humanity, has one of the simplest chemical forms compared to other crystals – it is purely made of carbon. They form within great depths of the earth’s mantle, some as far down as 500 kilometres beneath the surface of the earth. For these gems to crystalize, it requires tremendous amounts of heat and pressure, which can be 50,000 times that of the daily pressure we experience at the surface of the earth. Born from extremely harsh conditions, their origins are also ancient as they are known to be formed billions of years ago. These crystals then are transferred via volcanic eruptions to the surface of the earth, rapidly transferring molten rocks containing diamonds out into the crust. If these minerals cool down at a slow pace as they rise during the process, it could turn into graphite. If it gets in contact with oxygen as the temperatures are still high, it could potentially even vaporize into carbon dioxide. These types of volcanic eruptions that deliver diamonds to the surface are so rare, that such an event has never been observed in modern times. If diamonds can survive through this rigorous formation process as well as the volcanic eruptions that carry them to the surface for it to be discovered, they can potentially last forever. As one of the most beloved minerals throughout history, diamonds have been a constant subject of study for gemmologists. The first standardized grading systems for diamonds emerged in the 1950s. Diamonds are graded by a standard called 4Cs – which refer to its carat weight, colour, clarity and cut. The 4Cs combined helps define the quality and the value of a diamond. The 80.88 carat emerald cut diamond is an extraordinary gem that excels in every aspect of the 4Cs, and these categories reveal the true rarity of the diamond. “‘…A valuable stone is the one thing that endures. Lace is soon a rag, velvet impossible, flowers dead; but a jewel, if treated kindly, lives forever. It is indeed almost as indestructible as truth or a mighty love…” H. Bridgman, 1916 白鑽的魅力，在於閃爍熠動的火光，以及澄澈如水的純淨色澤。在鑽石4C中，D色無瑕鑽石意味著最佳的品質以及絕佳的增值潛力。若以機器測量鑽石內部所含的氮含量，則可將鑽石分為四類（Type Ia、Type Ib、Type IIa、Type IIb）。Type IIa型鑽石，不但完全不含氮，且顏色純淨，視覺上顯得更加輕透，如一池清澈晶瑩的泉水，或一顆凝固的水珠，玲瓏剔透，被形容為「purest of the pure」，數量僅佔寶石級鑽石中約1%，這顆鑽石無色而純淨、完全不帶一點黃色，甚比一般頂級的 D ／ Flawless 還要美上幾分！如此稀少也使得每顆Type IIa鑽石的出現，皆會附上特別報告書，也成為拍賣場上藏家競搶的最佳對象。 本件拍品為10.26克拉D色無暇Type IIa鑽石，能擁有這樣輕透、如一池凝結之水的鑽石，就與在這世界中找到一方天然毫無污染的人間天堂一樣不易了。 請參考2021年4月香港蘇富比 一枚13.47克拉 D / IF 白鑽鑽戒，以新台幣4300萬元落槌拍出。 請參考知名珠寶品牌CHOPARD一條主石5.84克拉 D色內無瑕鑽石套鍊，定價為新台幣9585萬元。
