During the last quarter of the 19th century, stimulated by exhibitions and museum collections of Renaissance art, the public interest began to look back the ‘golden age’ of the 15-16th centuries. Jewellers responded by creating rings resplendent with classical motifs such as carved cherubs, putti and acanthus swags. These settings often also incorporated a central point-cut diamond or cabochon gem and were decorated with various richly coloured enamels.
