Good Morning! what a lovely classic ring! Do you know how old it is? The important thing is to identify if the pearl is a cultured pearl or an imiation pearl. The age of the ring will help to determine this. If it is a Cultured Pearl it will be an early highly sought after CIRO cultured pearl ring and an early cultured pearl in general.
CIRO is still producing high end imitation jewelry and pearls today. CIRO was established in 1917 originally as a mail order company, selling costume jewellery, clip on earrings, and cultured pearls. When the company first launched the imitation pearl in the 1920s the CIRO brand became popular with flapper girls and early film stars of the 1920s.
