Vintage antique deco cobalt blue tile silver Bracelet screw back earring set Beautiful cobalt blue ceramic tile with a unique glaze set in a silver metal with a heavy darken patina. Artistic square tiles that sit at an angle that are connected at each point to create a deco bracelet with a fold over clasp. Slightly larger tiles hang from a one point from a screw back earring making a perfectly matched set. I am not completely sure what these lovely tiles are made from they almost look like a stone but are a little lighter than you think but still a nice weight. Metal is untested but looks like a silver with a heavy patina. No marking that I can see. Selling as a vintage antique costume jewelry. I believe this was made in the 1930 to 1940.
