This gold ring has an oval bezel that opens to form a concealed locket, containing an enamelled portrait of Charles I (reigned 1625-49). The hinged lid is set with a diamond on an enamelled ground.Commemorative jewellery depicting royalty was usually produced after the monarch's death, but was occasionally available during their lifetime, to be worn as a demonstration of loyalty. Commemorative jewellery, in the form of rings, lockets or hair clasps, was produced in great numbers after Charles' execution on 30 January 1649. Many examples have hinged lids: supporters of the Royalist cause, who wished to keep their allegiance secret, probably wore these during the Commonwealth under the rule of Oliver Cromwell. The Restoration of the monarchy in 1660 again produced great numbers of commemorative jewellery, made for those who claimed to have been Royalist supporters all along. Some rings commemorating Charles I were presented during his lifetime by his Queen, Henrietta Maria (1609-69), to Royalist supporters in appreciation of their continuing loyalty and financial backing, to be redeemed when the Civil War had ended.Much commemorative jewellery is decorated with black enamel in the same fashion as mourning jewellery. The shoulders of this ring have a scroll pattern reserved in gold on a ground of black enamel, the diamond is bordered with black enamel, and the border of the bezel is decorated with a black and white enamelled pattern.
