Timur ruby
The Timur Ruby is a cabochon-cut, unfaceted red spinel gemstone weighing over 352 carats, set as the centerpiece of a diamond necklace made for Queen Victoria in 1853 by the London jewelers R. & S. Garrard & Co., and currently held in the British Royal Collection.[1][2] Despite its name and longstanding reputation as one of the world's largest rubies, scientific analysis at the 1851 Great Exhibition in London confirmed it to be a spinel rather than corundum-based ruby, a distinction arising from historical misidentification before modern gemology.[1] Traditionally attributed to the 14th-century Turco-Mongol conqueror Timur, who acquired it during the sack of Delhi in 1398, the stone's engraved Persian inscriptions document ownership by later figures, including Mughal emperors Jahangir, Shah Jahan, and Farrukhsiyar, as well as Persian rulers Nader Shah in 1740 and Ahmad Shah in 1747.[1] Its provenance spans Timurid, Safavid, Mughal, Sikh, and British empires, passing to British control after the 1849 annexation of Punjab and presentation to Queen Victoria by the East India Company in 1851, underscoring its status as a symbol of imperial conquest and continuity.[1][2] The Timur Ruby's defining characteristics include its massive size among spinels, the rarity of its inscribed historical record providing a verifiable chain of custody from the 17th century onward, and its adaptation into European royal jewelry, though it has never been worn by a British monarch.[1]
