gamerlover:  I found this explanation: <br /> Sterling silver is an alloy of silver 92.5% and copper 7.5%. When it is worked by a jeweler it will be heated if it is soldered. As a result it may become coated in red copper oxide. Usually this is removed by pickling in a solution of sodium bisulphite which produces a weak sulphuric acid solution. If you have a ring that has not been properly pickled prior to polishing it may still have copper on its surface that will react with your perspiration to make a green copper compound that stains the skin. <br /> <br /> I would suggest soaking your rings in a mixture of household ammonia and water (50/50)for a day or two. The ammonia solution will turn blue as it forms a copper ammonia ion and this will not hurt the silver. After that, your rings will not turn your skin green because the copper has been removed from the surface of the sterling.

I don’t endorse what they recommend as I have no direct knowledge if it is safe or not.

Some people apply a polymer coating to their rings to act as a barrier between their skin and the metal of the ring. Nail polish is one option. Be aware you’ll need to reapply the coating from time to time, since it will wear away.

I have had trouble with this before and I found that a rhodium dip was all it needed. However, since it cost your FI $100, I would get an exchange it and see if that fixes the problem. It could just be a defective piece of jewelry.

Sterling Silver shouldn’t turn your finger green. The metal itself may tarnish with time, but a polishing cloth or a bath in warm saltwater mixed with aluminum foil brings back the shine of my sterling silver promise ring every time. 

Hope this helps!
