some interesting info on Koh-i-noor........
The first confirmed note historically mentioning the Kohinoor by an identifiable name dates from 1526. Babur mentions in his memoirs, the Baburnama, that the stone had belonged to an un-named Rajah of Malwa in 1294. Babur held the stone's value to be such as to feed the whole world for two days. The Baburnama recounts how this Rajah of Malwa was compelled to yield his prized possession to Ala ud din Khilji; it was then owned by a succession of dynasties that ruled the Delhi sultanate, finally coming into the possession of Babur himself in 1526, following his victory over the last ruler of that kingdom.
From the mid-tenth century, Malwa was ruled by the Paramara clan of Rajputs, who established a capital at Dhar. King Bhoj, who ruled from about 1010 to 1060. His successors ruled until about 1200, when Malwa was conquered by the Delhi sultanate.
there was another large pink diamond called Darya-ye Noor on the peacock throne of Akbar.
This diamond, like the Kohinoor, was mined at the Golconda mines in Hyderabad State, India. It found its way into the possession of the mughal emperors.
In 1739, the adventurer Nader Shah of Persia invaded India and sacked Delhi; the booty he garnered from the mughal treasury included the Darya-i-noor, in addition to the Kohinoor and the Peacock throne. All of these treasures were carried to Persia by Nader Shah and the Darya-i-noor has remained there ever since.
