What is micro mosaic jewellery?
By Jared James · Last updated 21 May 2026
Definition
Micro mosaic jewellery is made by fitting hundreds of tiny coloured glass pieces, called tesserae, into a glass or hardstone base to form a miniature picture or pattern. The work is extraordinarily fine, often with tesserae smaller than a pinhead, and was perfected in Rome from the late 18th century onward. Grand Tour travellers brought pieces home as souvenirs of Italy, so the style is closely linked with that era. Subjects include classical ruins, birds and floral motifs, typically framed in gold.
Frequently asked questions
- Where did micro mosaic jewellery originate?
- It was perfected by Vatican workshops in Rome from the late 1700s, developed to reproduce famous paintings in a durable medium. When wealthy Europeans began taking the Grand Tour, jewellers started making smaller pieces as portable souvenirs, and the style spread widely through the 19th century.
- How can you tell if micro mosaic jewellery is genuine?
- Authentic antique pieces show extremely fine, slightly irregular tesserae under magnification, with subtle variations in the glass colour and tiny gaps filled with a dark bonding material. Modern reproductions often use printed or moulded images rather than individual glass pieces.
- Is micro mosaic jewellery valuable?
- Fine antique pieces with detailed workmanship and intact gold settings can be quite valuable, especially those showing classical scenes or rare subjects. Condition matters greatly; missing tesserae reduce value, though careful restoration is possible.
