These pearls and other jewels, the whole being worth about 160,000 pounds, were awarded to the late King George of Hanover  in 1857, after a dispute of twenty years, as they had been claimed by the Queen  on the death of William IV. Part of them were brought originally from Hanover and the remainder had been the private property of Queen Charlotte, who left them to her son, Ernst, Duke of Cumberland, afterward King of Hanover.
A commission, consisting of Lord Wensleydale , Vice Chancellor Wood (afterward Lord Chancellor Hatherley) , and Mr. Lawrence Peel , was appointed by Lord Palmerston  to investigate the matter, and they unanimously awarded nearly all the jewels to the King of Hanover, a decision which greatly annoyed the Queen and Prince Albert.
George III, by his will, left Queen Charlotte all the jewels she had been given, and they were valued at 200,000 pounds; but many of them were seized by George IV and disappeared during his reign, as did a number of the crown jewels, including the celebrated Stuart sapphire, which was given by Cardinal York  to George III. George IV presented it to Princess Charlotte on her marriage, but after her death Prince Leopold was obliged to return it, and a few years afterward it reappeared in the headdress of Lady Conyngham .
