Meaning of Kohinoor and it's origin

                                                           

The Kōh-i Nūr, which means “Mountain of Light” in Persian, is a 105 carat (21.6 g) diamond (in its most recent cut) that was once the largest known diamond in the world.

The Kōh-i Nūr originated in the state of Andhra Pradesh in India along with its double, the Darya-ye Noor (the “Sea of Light”).
It has belonged to various Hindu, Mughal, Turkic, Afghan, Sikh and British rulers who fought bitterly over it at various points in history and seized it as a spoil of war time and time again.
It was most recently seized by the East India Company and became part of the British Crown Jewels when Queen Victoria was proclaimed Empress of India in 1877.

It was traditionally known as Madnayak or the King of Jewels, before being renamed Kohinoor in 18th century by Afghan Ahmad Shah Abdali
