Sterling Silver is very easy to test. Silver plated brass, nickel silver or low quality silver alloys will turn green when a drop of Nitric acid is applied. Sterling will turn a creamy color. Testing kits made specifically to test sterling silver are available from many jewelry supply companies.
When you heat Nickel nitrate, it will begin to boil and turn into a bright green liquid. Then it will begin to turn dark green until finally it turns into a black solid.
It is the nickel in some silver jewelry that reacts with your body chemistry to turn your skin and the jewelry black. .925 Sterling Silver, such as that offered by Tiffany and Silpada, contains no nickel. .925 sterling silver is 92.5 pure silver, with only 6.5% copper added for stablity.
True sterling silver will not leave green marks on your finger. Sterling from North America is fine silver ( .999 pure) a .925 % and copper makes of the rest of the alloy. Other locations will ofter mix fine silver with nickel. I assume whatever metal your ring is made of it oxidizing and the oxidation is rubbing off onto your skin causing a green mark to show.
Fake metal can turn your skin green this applis to gold and silver.
