Antique Art Deco 10K Rose and Yellow Gold Glass/Paste Ruby Brooch

Antique Art Deco rose and yellow gold brooch featuring a prong set marquise paste ruby in the center. This lovely brooch is marked “10K” on the pin back. There is part of another mark, possibly a maker’s mark, stamped to the right of the gold quality mark, but it is incomplete and I can’t identify it.
