The Indian government says it is still seeking to reclaim the Koh-i-noor diamond from Britain, despite telling India's Supreme Court otherwise.
The gem came into British hands in the 19th Century and is part of the Crown Jewels on show at the Tower of London.
Ownership of the priceless gem is an emotional issue for many Indians, who believe it was stolen by the British.
On Monday, India's solicitor-general had told the court that it was "neither stolen nor forcibly taken".
Ranjit Kumar, who was representing India's government in the hearing, had said the 105-carat diamond had been "gifted" to the East India company by the former rulers of Punjab in 1849.
But a statement by India's ministry of culture on Tuesday said the government "further reiterates its resolve to make all possible efforts to bring back the Koh-i-noor diamond in an amicable manner".
Mr Kumar's comments, which elicited surprise in India, did not represent the views of the government, the statement said. The official submission to the court has yet to be made, it added.

India's culture ministry appears to have misread the popular mood - the solicitor general's comments sparked a full-scale political row, forcing the government to backpedal.
The main opposition Congress party said Prime Minister Narendra Modi's government must make all efforts to bring the diamond back since "it's connected to our emotions".
Mr Modi's allies in Punjab state, the Shiromani Akali Dal, joined the criticism, describing the government stand as "wrong". One party MP said the Punjab government would even be willing to join the court case seeking its return.
Rattled by the criticism, the prime minister's office intervened, and the culture ministry issued a clarification.
The Koh-i-noor is undoubtedly an emotional issue in India where many believe that in 1849, the 10-year-old ruler of Punjab was forced to give it to the British and that it should be returned to India, its rightful owner.
