How we cut the Koh-I-Noor for the Queen of England
In 1852, our Master Polishers Fedder and Voorzanger went to London to repolish the Koh-I-Noor for Queen Victoria. This diamond is still the center stone in the Crown Jewels.
The Koh-I-Noor is an oval 109 carat diamond with a weight of 21.6 grams. It’s the main diamond of the British Crown Jewels, known from the crown. The stone is literally priceless and can therefore not be insured. Currently, the Koh-I-Noor is exhibited in the Tower of London together with the other crown jewels of Great Britain. During the biggest part of its long history, the Koh-I-Noor was the biggest diamond in the world. To this day, it is the most expensive diamond in the world. The Koh-I-Noor is a diamond with a fascinating history and an impressive journey.
The history of the Koh-I-Noor
The story of the Koh-I-Noor starts in India, seven centuries ago. In a little village called Kollur, close to Hyderabad, people found an unusual diamond. Everyone was amazed by its unusual color and large size. Until the 14th century, the diamond belonged to the Radja’s of the Kakatiya Dynasty in Warangal. In 1323, the Sultan of Delhi conquered Warangal. The Koh-I-Noor became part of the Sultan’s war bouts. It remained in the possession of the Sultan’s family until 1526. That year, it fell in the hands of the Mongol Emperor Babur. Babur wrote in his historiography about the value of the Koh-I-Noor. He believed it was valuable enough to feed the world’s entire population for at least 2,5 day.
Mountain of Light
For a few centuries, the Koh-i-Noor remained in possession of the Mongol Emperors. The emperors placed the diamond on their peacock throne. In 1739, the Persian Warlord Nader Shah successfully conquered Delhi. He threw Emperor Muhammad Shah into prison and took everything from him. But there was no sign of the precious diamond he heard so much about. Nader Shah discovered the Koh-I-Noor by accident. When he threw Muhammad Shah in prison, he wanted to switch turbans with the deposed emperor. Little did he know Muhammad hid his beloved diamond in his turban! When Nader found the diamond, he screamed: “Koh-I-Noor”, which is Persian for “Mountain of Light”.
The Koh-I-Noor in Persia
Nader Shah brought the Koh-I-Noor with him to Persia. Until his death, the diamond remained in his possession. After he passed away, Nader Shah’s grandson gave the diamond to Ahmad Shad Durrani in return for his support. Ahmad loaned the diamond to one of his descendants, Shah Shujah Durrani, who wore it in his bracelet.
Shah Shujah Durrani was the last Persian owner. He fought Mahmud Shah for the Persian throne between 1801 and 1809. After losing the battle, he fled with the Koh-I-Noor to Punjab, currently known as Lahore, in Pakistan. Once he arrived, soldiers of the Sikh Maharajah Ranjit Singh caught him. But Shah Shuja was able to buy his way out by giving the Koh-I-Noor to the Maharajah. In exchange, the Maharajah helped Shah Shuja get back the throne of Afghanistan. Ranjit Singh wore the diamond often in his turban and grew very fond of it. He wrote in his will he wanted to donate the Koh-I-Noor to the Jagannath Temple in Puri (India) after his death. His family did not like that idea and decided to keep the stone in Punjab.
Tally-ho! The Koh-I-Noor goes to England
In 1849, the British East India Company took the Sikh empire. The British imprisoned the last Sikh Emperor, Dalip Singh. They took the Sikh's properties as war compensations. One of the items of the war compensations was a bright, white stone: the Koh-I-Noor. In the Treaty of Lahore, a peace treaty marking the end of the war in 1846, they included the fate of the Koh-I-Noor. From now on, the stone would belong to the British conquerors. In England, the East Indian Company gave the diamond as a present of the war bouts to Queen Victoria in 1850.
Repolished by Coster Diamonds
The diamond was handed to Queen Victoria. She liked the diamond and sometimes wore it in a brooch. In 1851, the Koh-I-Noor went on display at the Great Exhibition in London. But the diamond was not cut in years. The outdated shape that was so typical for the Mughal era could not impress the people in the least. It was by far not as shiny as the other cut diamonds of that era. The queen was actually quite disappointed about it. Prince Albert, the queen's husband, suggested getting the diamond recut.
Therefore, in 1852, it was time to bring the ultimate sparkle to the Queen's diamond. However, this meant the Koh-I-Noor had to be recut by a professional. But it appeared that no Englishman was skilled enough to cut the diamond in an ideal way. Therefore, the Brits decided to look for the knowledge outside their own country. This is how they ended up in Amsterdam, asking Mr. Coster from Royal Coster Diamonds.
Mr. Coster was up for the challenge. He sent two of his best diamond polishers to England. His polishers, Fedder and Voorzanger recut the diamond from 186.00 carats to its current weight of 108.93 carats. As of that moment, the Koh-I-Noor really lived up to its name: it shines like a mountain of light.
Legends of the Koh-I-Noor
There are serval legends about the stone. One of the most famous ones is that the diamond can only be worn by female emperors and monarchs. They will reign long and prosperous. However, if a man wears the stone during his reign, he will die early. Moreover, his ruling period will go hand in hand with adversity and bad luck. This is the reason why, during its entire life in England, the Koh-I-Noor is only worn by female leaders. Another legend of the Koh-I-Noor is that for as long as it exists, it creates riches as big as its own value every day.
Craftsmanship as a legacy
For us at Royal Coster Diamonds, the Koh-I-Noor really is our darling. After all, two Coster polishers cut it for the English Royals. Amazing yet not surprising.

Two famous diamonds from Brazil that were brought to Coster to obtain its optimum glare.
