To date micro mosaic jewelry, examine the hardware. This style of jewelry first became popular during the 19th century (Italian artist Giacomo Raffaelli, founder of the School of Mosaics in Milan, in 1806, is said to have been the first to incorporate micro mosaics into jewelry). Over time, the types of hardware used in the creation of these accessories changed considerably. For example, brooches from the late 19th and early 20th centuries will often have a “C” clasp, while safety pin-style fasteners became popular in the 1920s. A certified appraiser or experienced antiques dealer can help you determine the age of a given piece based on the fasteners and clasps on your jewelry.
