Antique 2024 ring. Maybe Zircons. Another December birthstone.

Ring with 5 gemstones I believe to be zircons. Purchased in an antique shop many years ago. Middle gemstone is approximately 1 carat. 2 are approximately 1/2 carat and 2 are approximately 1/3 carat. Size 9 1/2. I have priced low because I've never had it appraised. 2024
