Likely dates to the 1930s. I have seen similar silhouette cameo pieces from this period, but this setting is definitely the most unusual I come across.

The metal is untested but has a lovely antique brass finish. There is some verdigris

The links are in two sizes (the second links from the pendant are larger than the others) and are etched

The silhouette cameo is printed on black glass

The setting is a cross on a shield with a crescent moon on each side.

Filigree clasp is stamped “Czech Made”

Maker: Czech made

Condition: Very Good with a few dings to the silhouette and some verdigris as well as a patina to the finish. Please see photos. Sturdy and clean.

Measurements:

Pendant: 1 7/8” wide x 1 1/4” high

cameo : 9/16” wide x 3/4” high

16” L
