What is mosaic jewellery?

Definition
Mosaic jewellery uses small pieces of stone, glass or ceramic, called tesserae, pressed or set into a base of mortar, metal or hardstone to form patterns, geometric designs or figurative pictures. The technique draws on one of the oldest decorative art forms, and in jewellery it ranges from bold Florentine hardstone mosaics (pietra dura) to the extraordinarily fine micro mosaic work developed in Rome from the 18th century. Both traditions appear in pendants, brooches, bracelets and rings, and antique examples remain highly collectible.
Frequently asked questions
- What is the difference between mosaic jewellery and micro mosaic jewellery?
- Micro mosaic is a specific type of mosaic jewellery that uses extremely tiny glass tesserae, sometimes smaller than a pinhead, to build up detailed miniature images. Regular mosaic jewellery uses larger pieces and tends to be more geometric or abstract in design.
- What is Florentine mosaic jewellery?
- Florentine mosaic, or pietra dura, uses thin slices of semi-precious hardstone fitted together to create colourful inlaid pictures, often flowers, birds or fruit. It is associated with Florence and the Opificio delle Pietre Dure workshop that refined the craft from the 16th century.
- Is mosaic jewellery fragile?
- Antique mosaic pieces require careful handling since individual tesserae can loosen over time as the bonding material ages. Modern pieces using resin or epoxy settings are more stable. Either way, mosaic jewellery is better suited to earrings and pendants than to rings that take daily knocks.
