This is a gorgeous boho piece, most likely made in the 1930s in Czechoslovakia. It is made with brass filigree that had been silvered and now some silver has worn off leaving it in a charming shabby chic condition. The stone is delicate blue glass and it has matching channels on the chain. The pendant itself is over 2 1/4” x 1.5” and the chain is 18”. I see lots of reproduction pieces out there but this is definitely an original.
