This is a beautiful antique Art Nouveau sterling silver and green agate stone ring, size K 1/2. Please note, due to its age, this is an unmarked piece that tests as silver. It features a smooth silver band that is set with a curved rectangular stone that measures 1.5cm long and 1.4cm wide. The smooth pale green agate stone is encased in a curved silver leaf wreath setting. This vintage ring is in excellent condition and it is a unique vintage treasure, it would look great worn alone or worn with other rings. Please check out my other items, thanks for looking.
