Wow! The quality of this Czech ring! I just love the golden filigree and bejeweled face of this ring along with the bezel set cameo which appears to be an early plastic of some sort, possibly celluloid or bakelite, not sure. The quality continues to the back side, hank and entire piece. The finger portion of the ring is a braided metal and the openwork and filigree continues throughout the entire ring. There are four bezel set amber glass jewels flanking the portrait cameo and the ring will adjust to any size. I tried finding something similar, but could find no signed Czechoslovakia rings with cameos for sale. This ring is fully signed on the under side and is a great piece of vintage costume jewelry especially if you collection other jeweled Czech items like perfumes, necklaces, pins or bracelets. The colors on this ring would be easily matched with your other items. The front piece measures over 1".
