Freirich started in France as Maison David, a manufacturer of fine trimmings and buttons, including components for hats and hat pins. It was purchased by Solomon Freirich in 1922 when the American branch became Freirich, the business in France remained Maison David. Many well known designers used their goods, including Chanel and Dior.
Garment trimmings remained their main product until 1955 when Solomon's son, Arthur Freirich joined the company and started the production of costume jewelry in the 1960s.
Their jewelry collections include fabulous and high quality Victorian Revival and Victorian inspired designs which are often mistaken for jewelry of the Victorian Period. The fact that the jewelry was unsigned in the beginning just seems to add to the confusion. One way to tell them apart is by the materials and the findings used, if the piece is not signed.
Of particular note are their Champleve enamel pendants and brooches in vivid colors. These display a characteristic wavy textured background, which makes them easy to recognize when they are not signed.
The company closed in the 1990s. Some of the earlier pieces can still be found. I personally favor the enamel ones but the quality in all of them is excellent.
