This magnificent Kundalini Snake Ring  is  made by craftsman from Jaipur in India.

It is made of brass (an alloy of copper and zinc). Brass is a good alternative to gold, it  does not change color and does not break down over time. She  does not cause allergy, so you can wear it without fear.

They are  very easy to clean by rubbing it with a little toothpaste and lemon juice.
 
The size of the ring is adjustable.
