A group called the Tipu Sultan United Front had urged the Indian government to take steps to help prevent the sale of this ring as it is a piece of history.
The group also said that if the ring has been put up for auction, Indian philanthropists should have been encouraged to purchase it on behalf of the country.
The ring was previously listed for sale by Christie's in 2012 but was then withdrawn from sale.
Tipu Sultan (Nov 20, 1750-May 4, 1799), also known as the Tiger of Mysore, was a scholar, soldier and poet.
He was the eldest son of Sultan Hyder Ali of Mysore.
