Antique ring. This was part of my collection. Size unknown. Maybe around size 11? It has a substantial weight and feels solid. It's super cute to wear it lined up on four fingers like Yubaba (from Spirited Away). Thank you for looking. Using relevant tags. Feel free to comment with offers or questions.
