In the world of diamonds, Natural Fancy Red diamonds are among the most rare. Less than 0.1% of all diamonds found in the world can be considered Natural Fancy Red and the bulk of those weigh less than half a carat.
The red color in these diamonds is not caused due to a foreign element present during its formation, it is due to irregularities present within the inner structure of the diamond, the crystal lattice.
Here’s a look at the five most famous red diamonds.
The largest red diamond ever recovered, the Moussaieff Red weighs in at 5.11 carats, fancy red internally flawless. Originally found by a Brazilian farmer in the 1990s by the Abaetezinho river in a region known as Alto Paranaiba. The stone, originally called The Red Shield, weighed in at 13.9 carats in its rough form. It was purchased by famed jeweler Shlomo Moussaieff in 2001-2002 and remains part of his company’s inventory to this day.
紅鑽中最赫赫有名，也是目前已知世上最大顆的紅鑽。約20世紀90年代，由巴西農民所發現，原石重13.9克拉，被紐約珠寶商William Goldberg Diamond Corporation收購，經三角形明亮式切割（triangular brilliant-cut)後，成為重5.11克拉，淨度為全美的鑽石，並取名為「紅盾」（Red Shield）。之後2001年或2002年，再由倫敦珠寶公司穆薩耶夫（MOUSSAIEFF）購入，並將其更名為The Moussaieff Red。
Noted diamond writer Stephen Hofer called the Rob Red Diamond “the most saturated and purest red diamond measured visually and instrumentally to date in the world’.
