The diamond may have been excavated from a chain of 4 km (13 ft) deep gravel piles on the banks of the Krishna River in Golconda, India (now Andhra Pradesh). It is impossible to know when and where it was found, and there are many unconfirmed theories about its true owner.
Babur, the Torco Mongol founder of the Mughal Empire, wrote about a "famous" diamond that weighed more than 187 carats - the volume of Koh-i-Noor of about carats. Some historians believe that Babar's diamond is an early reliable reference to Koh-i-Noor. According to his diary, it was acquired by Allauddin Khilji, the second ruler of the Khilji dynasty of the Delhi Empire, when he invaded the kingdoms of southern India in the early fourteenth century and was probably occupied by the Kakatiya dynasty. It later reached the royal families of the empire, and Babar received a diamond in 1526 as a tribute to the conquest of Delhi and Agra in the Battle of Panipat.
The fifth Mughal emperor, Shah Jahan, placed a stone in his ornamented peacock throne. In 1658, his son and successor Aurangzeb confined the ailing emperor to the Agra fort. While in Aurangzeb's possession, it was allegedly cut by the Venetian Lepidary, Hortons Borgia, which reduced the weight of this large stone to 186 carats (37.2 g). Due to this negligence, Borya was reprimanded and fined Rs. 10,000. According to recent research, the story of the bourgeoisie cutting diamonds is incorrect, and probably merged with Orloff, part of Catherine Durant's Imperial Russian Regiment in the Kremlin.
One of Ranjit Singh's favorite horses is the head of his stable. Her jewelry is on a scale, including Koh-i-Noor (center above).
After the invasion of Delhi in 1739 by Afshrid Shah, Nadir Shah of Persia, the treasury of the Mughal Empire was looted by his army in an organized and complete acquisition of the wealth of the Mughal emperors. Along with millions of rupees and a variety of historical jewelry, Shah also took Koh-i-Noor. When he achieved the famous mountain, he introduced "Koh-i-Noor", Persian and Urdu as "Mountain of Light". One of its ports said, "If a strong man throws four stones - one north, one south, one east, one west, and a fifth stone into the air - and if the space between them is filled with gold." Not all mountains are equal to the value of light.
