Sculpted xture set in solid pure copper
Inside diameter is mm. Ring size chart on last photo.
I have oxidized it to give it a vintage look. It can be shined up easily to a brighter copper.
Copper is known to be medicinal mineral often used to ease arthritis. if you get green fingers this this is harmless and can be a sign that your acidic levels in your body is out of balance. That a why it happens to some people and not others. You can coat the inside of the ring with clear nail polish if you find this to be a problem.
