Timur ruby

The Timur Ruby (also Khiraj-i-alam, "Tribute to the World") is an unfaceted, 352.54-carat (71 g) polished red spinel set in a necklace.

Spinels are found in various parts of the world, including the Transoxiana region that was home to the Mughal ancestors.

The stone passed to subsequent Mughal Emperors, including Shah Jahan (who had it set in the Peacock Throne) and Aurangzeb.

Nader took the Peacock Throne as part of his treasure, but removed the Timur ruby and the Koh-i-Noor diamond to wear on an armband.

When the East India Company invaded Punjab in 1849, they took possession of the Timur ruby and the Koh-i-Noor diamond from Duleep Singh.

After the Great Exhibition closed the Court of Directors of the East India Company presented the gem to Queen Victoria as a gift after which it became her private possession.
