A brief history of micro mosaic jewelry. Micro mosaic jewelry became popular during the European Grand Tour period (17th-19th Century). Members of wealthy families would travel around Europe taking in the sights and cultures of several different countries. Italy was a very popular tourist spot as it had a long and prestigious history in arts and culture - a favorite subject in aristocratic circles. It was also a famous glass producer, and Italian craftsmen quickly turned their glass making skills to making stunning miniature micro mosaic pictures for their rich visitors. Flowers, birds and architecture were a very popular subjects. Each piece of tesserae (little hand-pulled glass tiles) was hand cut by the artist and painstakingly set in place. No two micro mosaic pieces are the same. This item is in the category "Jewelry & Watches\Vintage & Antique Jewelry\Brooches & Pins".
