The Timur Ruby (also Khiraj-i-alam, "Tribute to the World") is an unfaceted, 361-carat (72 g) polished red spinel set in a necklace for Queen Victoria in 1853. It is named after the ruler Timur, founder of the Timurid Empire. It was believed to be a ruby until 1851.
It is inscribed with the names and dates of six of its previous owners:
When the British annexed the Punjab in 1849, they took possession of the Timur ruby and the Koh-i-Noor diamond from Duleep Singh. The two gems have been owned together since 1612. The East India Company presented the Timur Ruby to Queen Victoria as a gift in 1851. It was set in a necklace in 1853. After the necklace was lengthened in 1911, it was rarely worn.
