The auction titled 'Maharajas and Mughal Magnificence' and organised by the Christie's will showcase an "unparalleled collection" of stunning jewels, diamonds, finest jewelled objects, gemstones, swords, daggers and decorative objects spanning over 500 years -- from the Indian royalty and the Mughal period, the global auction house said.

"Spanning over 500 years of history and sovereign power on the subcontinent, 'Maharajas & Mughal Magnificence' tells the story of a continuous tradition of patronage from the Mughal Empire to present day, with provenance including the royal and noble families of India," the Christie's said.

The objects are offered from the Al Thani collection.

Among the objects will be the hilt of the state sword of Maharaja Jagatjit Singh of Kapurthala. Estimated at between USD 100,000 and USD 150,000, the sword is enamelled and set with diamonds. Its lion-headed pommel is set with ruby eyes. One side of the hilt is set with a raised and molded crest of Kapurthala and the other side with the words 'Kapurthala State' set in diamonds.
