This is a very unique ring that is intriguing. It is copper or copper colored. It does not stick to a magnet. It appears to be artisan but has an ornate antique looking overlay over the shank that I can see under a glass. I couldn?t pic it up well in the photos. I don?t know what the stone is but the ?sea green? color has some depth. The ring is a size 8.5. The crown is 13mm. Nice pre owned condition. Thank for looking!
