When Edward VII, as Prince of Wales, embarked on his tour of India in 1875-6, he commissioned Garrard's, the Crown Jewellers, to make various items of jewellery for presentation during his trip. According to Shirley Bury's research in the Royal Archives list, twenty-two rings with portrait miniatures of the Prince were made during this period (the miniatures were smaller versions of ones mounted in bracelets). Fifteen of the rings had diamond surrounds in garter form with crown surmount, and apparently diamond-set portrait rings were given at Calcutta to the Maharajas of Kashmir, Jaipur and Holkar in December 1875
