Stuart crystals were flat topped carved rock crystal quartz capping a gold wire cipher and/or crown on a hairwork background. These were mounted as rings, cufflinks, pendants, earrings and slides. Usually mounted in gold, some have black or white tracery enamel. These rings were produced in support of the monarchy after the execution of King Charles I in 1649 and are a precursor of the memorial or mourning ring.
