At first, Ke Inor fell into the hands of Indian Mughal emperors. It has been preserved in the Mughal palace for nearly a hundred years. Like the famous diamond Shah, when Nadir Shah of Persia captured Delhi in 1739, he moved this "Ke Inor" and Shah to Isfahan, Persia. Nadir Shah was assassinated in 1747, and his empire fell apart.

During the chaos in Isfahan, a nobleman, Afhan Amasyabedel, failed in his attempt to seize the throne, so he robbed a batch of treasures and led his army eastward to Kandahar city to rule Afghanistan. Among the treasures he brought, there is this "Ke Inor" diamond and Tamil ruby. Later, the king who succeeded to the throne moved the capital several times, from Kandahar to Kabul, and finally to Lahore (now in India), where these treasures were preserved until 1849. At this time, the British had already invaded India. In the war of British annexation of Punjab, India in 1849, the above-mentioned treasures were taken away by the British East India Company, and the British governor Lord Daihe Xu presented this ancient big diamond to Queen Victoria of England under the name of "Mountain of Light".

The "Mountain of Light" was originally ground into an ancient diamond shape by an Indian jeweler, and its flash is poor and not beautiful enough. In 1852, it was reprocessed by British court mineralogist Ding tennant. Although the mountain of light has become much more beautiful, its weight has been reduced from 191 carats after the first pondering to 16 carats. After the new grinding, the Queen used it as a brooch. After the Queen's death, the "Mountain of Light" was set on the cross of the crown of Queen Mary, England. After King George VI ascended the throne, he made a crown for Queen Elizabeth in 1937, and the famous diamond "Mountain of Light" was set on the crown of Queen Elizabeth. There is such a passage in the positive Hindu scripture: "Whoever owns it will own the whole world; Whoever owns it will have to bear the disaster it brings. Only God or a woman has it and will not suffer any punishment. " It refers to one of the largest, most famous and oldest diamonds in the world: Ke Inor diamond, which means "the mountain of light" in Persian. At the grand funeral of the Queen Mother at Westminster Abbey in London, the whole world witnessed the radiant charm of the "Mountain of Light". The "mountain of light", a symbol of wealth and power, is also the bane of bloodshed and death. According to the literature, this diamond has caused countless bloody massacres and struggles in the past 7 years. Many monarchs who once owned it ended up with bad luck.
