A replica of Koh-i-Noor, one of the largest cut diamonds in the world, has gone on display at the Pakistan Museum of Natural History (PMNH) in Islamabad.

The disputed original diamond, which weighs 105.6 carats (21.12g), and is believed to have been mined from the Kollur mine, Golconda, India and was acquired by Alauddin Khalji, Sultan of Delhi, is part of the British Crown Jewels.

The legendary diamond had also been part of the Mughal Peacock Throne (Takhat-e-Taoos) where it was lodged at the very top of the throne, in the head of a glistening gemstone peacock.


Persian ruler Nadar Shah invaded Delhi in 1739 and took the Peacock Throne along with other treasures but removed the Tamur Ruby and the Koh-i-Noor to wear it on his armband.

The diamond remained in Afghanistan for almost 70 years after which, in 1813, Sikh ruler Ranjit Singh won back all the Indian land and brought back the Koh-i-Noor to India.

Today, the diamond is on public display in the Jewel House at the Tower of London, where it is seen by millions of visitors each year.

The governments of Pakistan, India, Iran and Afghanistan have all claimed rightful ownership of the Koh-i-Noor and demanded its return ever since India gained independence from the United Kingdom (UK) in 1947. The British government insists the gem was obtained legally under the terms of the Last Treaty of Lahore and has rejected the claims.
