LONDON — A group of stars and business figures want Queen Elizabeth to return the Koh-i-noor, one of the world best known diamonds, back to India.

The 105-carat diamond, which is currently part of the of the British crown jewels, is on display in the Tower of London.

The gem was worn by the late Queen Mother at the coronation of her husband. It was mined in India, seized by the East India Company and given to Queen Victoria in the 1800s.

Now, a group of Indian businesspeople and entertainment figures have, according to multiple reports, instructed a legal team to begin proceedings in the high court in London to get the gem returned.

The group, which has named itself the Mountain of Light, say the stone was seized from India under dubious circumstances and should be given back.

“The Koh-i-noor is not just a 105-carat stone, but part of our history and culture and should undoubtedly be returned," Bollywood star Bhumicka Singh said.

The group is expected to make their case, saying that Britain stole the gem, according to the Times of India, which added that they may take it to the International Court of Justice.

Five years ago, British Prime Minister David Cameron rejected calls from Indian politicians to return the diamond, saying such a move would leave the British Museum empty as it would set a set a precedent.

Displayed in London at the Great Exhibition in 1851, the rose-cut of the Koh-i-Noor didn't impress visitors, so it was re-cut as an oval the following year. It is said to be unlucky for men to wear.
