Micro Mosaics are practically grains of stone and glass which are usually seen in jewelry (bracelet, earrings, brooches, crucifix) although they were regularly incorporated into ecclesiastical objects such as crucifixes and shrines. Micromosaics are tiny glass beads and semi-precious stones inlaid into precious metals. (see Micro Mosaic Jewelry)
At ebay there are many vintage and antique Micro Mosaic Jewelry set, brooches, earrings, crucifix, etc. which up for bidding. The jewelry pieces were mostly Italian made.
