"The most wanted diamonds in the world are also the most expensive ones. So, let's check the top most expensive diamonds in the world."
FP included the following diamonds in its list
The Heart of Eternity: Mined in the South African Premier diamond mine it was cut into a 27.64-carat heart shape and graded by GIA as a Fancy Vivid Blue. Last time sold for $16 million.
The Orange: There is little information about the provenance of this 4.82 carat, Fancy Vivid Orange pear shape. It is largest stone known in this color category/ Last time sold at $32 million.
The Steinmetz Pink: This 59.60-carat Vivid Pink is the largest known diamond in this color category. Last time sold for $70 million.
De Beers Centenary Diamond: At 273.85 carats, it was only thanks to the legendary master cutter Gabi Tolkowsky that the irregularly shaped rough stone was cut into the heart shape it has today. Valued at $100 million.
The Hope Diamond: A cushion cut blue diamond of 45.52 carats, the legendary Hope diamond is a center piece of the collection of the Smithsonian Museum of Natural History in Washington DC. Valued at $350 million.
The Cullinan: Part of the world's largest rough diamond ever found, in what is today the Premier mine, the cut stone is part of the British crown jewels. Valued at $400 million
The Sancy Diamond: The 55.23-carat, pale yellow gem once reputed to have belonged to the Mughals of antiquity, but it is more likely of Indian origin owing to its cut, which is unusual by Western standards. The shield-shaped stone comprises two back-to-back crowns (the typical upper half of a stone) but lacks any semblance to a pavilion (the lower portion of a stone, below the girdle or midsection). On display at the Apollo Gallery at the Louvre in Paris, it is part of the French Crown Jewels. Value: $5.3 million.
Koh-i-Noor: "It was discovered more than 5000 years ago and its current name means "Mountain of Light" in Persian. The first record mentioning it was in the Andhra Pradesh state of India. No one knows what it's original weigh was, the first time when it was weighted it was 38.2g and 186 old carats." Value: priceless
