Shah Jahan's Gemstones
Shah Jahan's Gemstones
The Mughal court's gem inventory and its dispersal after 1739
Shah Jahan, fifth Mughal emperor of Hindustan (r. 1628–1658), assembled and commissioned what is generally regarded as the most extensive gem inventory ever held by a single court. The collection — diamonds, rubies and red spinels, emeralds, sapphires, and pearls of exceptional size — was deployed across thrones, jewelled objects, court regalia, and personal ornaments, and its dispersal after the Persian invasion of 1739 is the single most consequential event in the modern provenance of historic Asian gemstones.
The court inventory
Mughal court records, supplemented by the accounts of European travellers — most notably the French jeweller Jean-Baptiste Tavernier, who visited the court in the 1660s — describe a gem holding of staggering scale. Diamonds came principally from the Golconda fields of the Deccan, the dominant world source until the Brazilian discoveries of the eighteenth century. Red stones were a mixture of Burmese ruby and Badakhshan spinel, the latter often misidentified as ruby in the period; the so-called Timur Ruby in the British Royal Collection is in fact a spinel of this Badakhshan provenance. Emeralds came from Colombia via the Manila and Goa trading routes, with carved Mughal emeralds of substantial size — the most famous being the so-called Mughal Emerald of 217 carats, dated 1695 — among the most distinctive of Mughal court productions. Sapphires came from Sri Lanka and Kashmir; pearls from the Gulf and Mannar fisheries.
The Peacock Throne
The most celebrated single object commissioned by Shah Jahan was the Peacock Throne (Takht-i Tawus), completed around 1635 and described in detail by Tavernier and by court chronicles. The throne was constructed of gold and set with thousands of stones, including very large diamonds, rubies, emeralds, and pearls; the Koh-i-Noor was reportedly set in the canopy. The combination of weight, scale, and gem density made the throne the single most concentrated display of gem wealth in the early modern world. Estimates of total stone count run into the tens of thousands.
The throne stood in the Diwan-i-Khas of the Red Fort in Delhi until 1739. It was stripped and dismembered after Nader Shah's invasion, with the gold and stones distributed across Persian and Afghan treasuries; reproductions and successor thrones were commissioned by later rulers but the original was never reconstituted.
Inscribed and named stones
Shah Jahan continued the Mughal practice of inscribing royal diamonds and spinels with the names of successive owners. Several surviving stones bear his name in Persian script, dated to his reign, alongside earlier and later inscriptions. The Shah Diamond in the Russian Diamond Fund records his name in its 1641 inscription. The Akbar Shah Diamond, before its recutting, carried inscriptions from Akbar and Jahangir; comparable inscribed pieces appear in the published catalogues of the Iranian Crown Jewels.
Shah Jahan also commissioned engraved emeralds — Mughal court engravers carved Persian poetic and Quranic inscriptions, floral motifs, and chevron borders into emerald cabochons and tablets. These carved Mughal emeralds are now distributed across museum collections and private hands, with notable examples in the Al Sabah Collection in Kuwait, the Metropolitan Museum, and the Aga Khan Museum.
Dispersal in 1739
Nader Shah's invasion of Delhi in 1739, his sack of the city, and his removal of the imperial treasury to Persia is the single defining event in the modern provenance of Mughal-court gems. The Peacock Throne, the Koh-i-Noor, the Darya-i-Noor, the Great Mughal Diamond (likely the antecedent of the Orlov), and a substantial fraction of the catalogued treasury crossed into Persia. The fragmentation that followed Nader's assassination in 1747 dispersed the treasure further, with stones moving through Afghan, Sikh, Persian, Russian, and ultimately British and French royal and imperial collections.
What survives and where
Stones with secure Shah Jahan provenance are held in the British Crown Jewels (Koh-i-Noor, Timur Ruby), the Russian Diamond Fund (Shah Diamond, possibly the Orlov), the Iranian National Treasury (Darya-i-Noor and others), and various major museums and private collections. Carved Mughal emeralds and inscribed spinels with Shah Jahan's name appear in auction sales and in published museum catalogues; recent decades have seen substantial scholarly work on inscription dating, palaeography, and stone identification, refining attributions that earlier nineteenth-century cataloguing had often misallocated.
In the trade
For the trade, Shah Jahan's name in a stone's provenance — whether by direct inscription, by documented inclusion in the Mughal treasury, or by association with the Peacock Throne — is among the highest-value provenance markers in coloured stones and historic diamonds. Auction estimates and private-sale prices for stones with verifiable Mughal provenance are routinely multiples of equivalent stones without the historic association. Authentication relies on inscription palaeography, period-consistent cutting and setting, and documented chain of custody back to nineteenth- or eighteenth-century inventory.
