Finger-ring, gold with traces of black enamel, the bezel set with seven mirror-backed facetted glass pastes. These so-called 'Vauxhall pastes' were flat-backed glass paste gems whose facetted surface was reflected in the mirrored back giving an illusion of great depth. Though there are many surviving dated examples of these settings from the late-18th century, such an early piece is a great rarity.
