British took many valuable things with the Kohinoor: these included an emerald-studded waistband, a necklace of 222 pearls

Ahead of Prince Charles's coronation, the Guardian has revealed in its 'Cost of Crown' series that apart from the Kohinoor, many other valuables were looted from India. Along with sculptures, and paintings, there was also a gold waistband studded with 19 emeralds. It was used to decorate horses in the stables of Maharaja Ranjit Singh of the then princely state of Punjab.
In a 1987 study of the Royal Jewellery, Leslie Field mentioned necklaces with two rows of pearls. It also had 222 pearls and rubies surrounded by diamonds. It is claimed that this too belonged to Ranjit Singh. On the other hand, the matter of grabbing Punjab by putting pressure on Ranjit Singh's youngest son Duleep is well known.
The series mentions an investigation, in which Queen Mary (Elizabeth II's grandmother) is quoted as mentioning the source of her royal jewels. According to the documents, a necklace studded with four big rubies is also in the treasury. It has the largest spinel ruby (flexible and lightweight) of 325.5 carats. It is also called 'Taimur Ruby'.
Queen Elizabeth was seen handling it in the 1969 BBC documentary Royal Family. It remained with many Mughal rulers until it was passed on to Queen Victoria.
A 1912 report describes how the priceless gems included in Charles's royal collection were brought from India as a symbol of victory and later given to Queen Victoria. As part of the conquests, the Company plundered countless gems, sashes and the priceless Kohinoor. These things are now the property of the royal household. The Kohinoor, on the other hand, is part of the Queen Mother's crown and has come to symbolize Britain's tortuous relationship with its royal history.
All these things were kept in the exhibition organized when Buckingham Palace has opened in the summer about 5 years ago. Prince Charles' favourite gems were also kept in the Royal Collection. According to the report, this has been revealed on the basis of a 46-page file of the archives of the India Office, the responsible government department during British rule.
The British royal family is one of the most prestigious families in the world. Charles, 74, has received Rs 6,221 crore for services from the private fund Duchy of Cornwall. His total engagements stood at 10,934. After becoming the king, he will get Rs 200 crore annually for his expenses. As Queen, Camilla has got a large house in Wiltshire. The money received by the rest of the members has not been disclosed.
