> When: 13th century
A lot of blood has been spilled over the Koh-i-Noor Diamond. Reportedly discovered in the Kollur Mine, a series of gravel-clay pits now submerged by the Krishna River in the Indian state of Andhra Pradesh, it was the possession of the ruling Kakatiya dynasty for many years and passed through the hands of Sikh, Mughal, and Persian rulers. In 1849, the British obtained the diamond after the Second Anglo-Sikh War. In 1852, Prince Albert ordered that the diamond be cut, resulting in a 186-carat oval-cut diamond. The diamond is the property of the British crown 174 years later.

The year 2015 would prove to be an important one for the Lucara Diamond Corp. and the Karowe Mine in Botswana.
