A slave working within the Guntur district’s Kollur Mine found the Regent diamond there in 1698. The slave hid it in an enormous leg wound. After studying in regards to the gem’s existence, an English sea captain killed the slave and stole the diamond from him. Then it was bought to Jamchand, an Indian service provider who later bought it to Thomas Pitt, the Madras President, in 1701. The gem’s present moniker has been connected to it ever since Philippe II, the French regent, bought it in 1717. Later, the Regent diamond was positioned in a crown for Louis XV’s coronation in 1723 and in a distinct crown for Louis XVI’s coronation in 1775. Napoleon Bonaparte completely acquired the diamond in 1801. Later after his exile, Archduchess Marie Louise of Austria, Napoleon’s second spouse, carried it again to Austria. Nonetheless, the French Crown Jewels acquired it again from her father afterwards. The diamond was subsequently set into the crowns of Napoleon III, Charles X, and Louis XVIII. It has remained within the Louvre museum since 1887.
