GREY, Charles (1804–1870), army officer and courtier. Autograph letter in third person, 1 side, 8vo,Windsor Castle, Oct 17th 1851, on black edged mourning paper, “Colonel Grey has received the Command of His Royal Highness Prince Albert to return the Collection of Ceylon precious stones sent for his inspection by Mr. Purdue, with the expression of His Royal Highness’ best thanks”.
Grey was an equerry to the queen from 1837 to 1867, and private secretary to Prince Albert from 1849 to 1861. After Albert's death he became private secretary to Queen Victoria (ODNB). This letter was written two days after the Great Exhibition closed to the public, a project masterminded by Prince Albert, and it quite possible that the gem collection referred to might have some connection through one of the exhibitors.
