1/8 Royal Cubit Tensor Ring 2.8×23.8mm 1.5mm twisted copper wire. I use silver solder, like for a jewelry production.

I don't send it in a jewelry box.

I have my tensor ring for over 5 years.

Helps to improve water

Made my first one to eazy pain after having a  bad bicycle accident. Helped me walk without pain for over 5 years . Now I can run again.

I don't know it can help other people.

I don't claim it has some power or can heal people.

I think it emits very delicate energy field in shape like a  donat, and it supports someway energy field of a living things.

It can help to lower harmful energy emitted by electronic devices and geopathic stress.

I don't claim it has some specific vibration, I can't check it to prove.

It will change color, patina can have different colors.

Clean it with old toothbrush and soap.

Soak for a few minutes in solution vinegar and baking soda 2:1 you can reuse solution a few times. Clean with water again.
