This Solid Sterling Silver button Pendant is an original, art Nouveau piece dated 1904. The pendant, clasp and chain are Solid Sterling Silver. I found these several years ago, and wanted to find a way that they would be worn again. So I have gently repurposed them into pendants, by soldering a single loop bail onto the back. The original button is still completely intact. I love the history of these necklaces. Truly unique, limited addition - as I only have 4.
