The Koh-I-Noor

The diamond’s name is ironic. The name Koh-I-Noor is a Persian word that loosely translates to ‘Mountain of Light.’ This name comes from the position of the diamond since it was discovered in the 1300s. The discovery site of this precious stone is the Golconda diamond mine located in modern-day India. It was the largest diamond in circulation until the 1800s when a rival appeared.

Prince Albert of England then reduced the diamond from the original 105.6 carats to 86 carats to increase its brilliance and sparkle. It was, however, a widely held belief that it is a cursed stone that brings misfortune and sadness to the owner. Expensive Diamond

This claim proved to be mysteriously true, or it looked so until Great Britain gained possession of the stone in 1849. The diamond is oval-shaped, and it is currently at the HM Tower in London. It is a popular tourist attraction for tourists from around the world. It was also a part of the queen’s mother’s crown. Authors William Dalrymple and Anita Anand co-wrote a book on the diamond and the mystery stories surrounding it. Expensive Diamond Expensive DiamondThe Sancy Diamond

A pale-yellow diamond shaped like a shield, the Sancy diamond is one of the first diamonds cut to uniform facets. The diamond has no pavilions and possesses only two crowns, giving the diamond a peculiar shape. Legends have it that the gem initially belonged to the Mughals. However, researchers assume it most likely originated from India due to its shape. Moreover, most of the diamonds mined before the discovery of American and Kimberly mines are from Golconda.

Many great kings and individuals owned this priceless diamond. Some of the previous owners of this stone include Charles the Bold, Manuel I of Portugal, King James I & II, King Charles I, Duke of Burgundy, and seigneur de Sancy (whose name inspired the diamond’s name today). The diamond disappeared during the French revolution, and it was eventually sold to the Louvre for $ 1 million in 1978 after stints with multiple owners. It currently sits in the Apollo Gallery, neighbored by the Regent and Hortensia. Expensive Diamond

The Cullinan Diamond

When this diamond was discovered in the Premier No. 2 mine in Cullinan, South Africa, it was the largest gem-quality rough diamond ever mined in history. At the time of discovery, it weighs 3,106.65 carats or roughly (621.35g). It was later to be a mother to 9 diamonds, which are all part of the crown jewels of the UK.

The Cullinan 1 at 530.2 carats was the largest diamond till 1985 before being dethroned by the Golden Jubilee (545.67) from the same mining site. However, it remains the largest clear-cut diamond to this date. It currently sits at the top of the sovereign Sceptre with the cross.

Hope Diamond

The name probably gets you thinking positively about the diamond’s story. However, it is a popular belief that this diamond carries the curse of wrecking its owners. The diamond is not just blue due to its boron content, but it also turns red under ultraviolet light due to the stone’s phosphorus content. The diamond originated from India in the 1600s, precisely from Andra Pradesh’s Kollur mines.

Expensive Diamond

The diamond’s name came from the Hope banking family in London, who owned the diamond briefly around 1839. A French merchant by the name of Tavernier possessed the gem sometime around 1653. According to Wikipedia, 22 different people had owned the diamond before the Smithsonian Museum acquired it in 1958. The Hope Diamond has been in the museum until today. The diamond was one of the jewels that were stolen in 1792, and its insurance is worth a whopping $250million. Expensive Diamond

The Centenary Diamond

The Centenary diamond is a rough diamond that weighed over 500 carats. It was later shaped into a heart, reducing its weight to 273.85 carats. The reduction effort was later complemented by an increase in the coloring and clarity grade of the jewel. A team of highly skilled jewelers spent 154 days re-cutting this gigantic jewel. The current owner of the diamond is unknown, making its exact location impossible to decipher. Expensive Diamond

The Steinmetz Pink Diamond

The pink star weighs 59.60 carats and is rated Fancy Vivid Pink by the America Geology Institute, making it the largest diamond of this rating in history. It was mined in the De beers mines in 1999, making it a millennial gem. The gem is so big that it took Steinmetz Diamonds 20 months to cut the diamond. It was displayed publicly in Monaco on 29 May 2003. On 3 April 2017, Chow Tai Fook Enterprises bought the stone at a Sotheby’s auction in Hong Kong for $71.2 million. Expensive Diamond

The Oppenheimer Blue Diamond

The 14.62 carat Oppenheimer Blue is the largest diamond to ever appear in an auction. The original owner was Sir Philip Oppenheimer, and it sold for $57.5milion at Christie’s in Geneva. It held the record for the largest diamond ever sold until 2017 when Steinmetz Pink Diamond hijacked the record. The diamond is in a ring flanked on both sides by smaller diamonds.

It was named after its last owner, who controlled mining activities at De beers and gave the diamond to his wife as a gift. The diamond was presumed to fetch around 38 – 48 million Swiss Francs but smashed all expectations with the final bid. The bidding session lasted just 25 minutes. Expensive Diamond
