Yes. Silver tone jewelry will turn your finger green because the metal under the silver tone is probably a brass which contains copper. It is the copper that turns your finger green.
Silver stamped 975 will not turn your finger green.
The reason your skin turns green is because the item's base metal is copper, even though it may be plated with gold or silver which will wear off and expose the copper based metal underneath.
No
it is not gold, it could be gold plated or brass
Yes it means that its not made out of real sterling silver (if its real it should be marked 925 in the back) if its not the your finger wil turn green and hopefully you didn't pay a lot for it!
Most metals like gold and platinum will not turn your finger green unless you have a metal allergy. Most people are allergic to the alloys added to thee metals for strength like copper. Sterling silver and platinum are two of the hypoallergenic metals.
Rhodium is a hypoallergenic metal that is unlikely to cause discoloration on your skin. However, any metal can react with the acids in your skin and potentially leave a green mark. Keeping your rhodium-plated jewelry clean and dry can help prevent any skin discoloration.
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.
If a person has a natural high acidity level in his/her skin, it is possible for his/her finger to "turn green" from silver or gold jewelry, especially when the weather is hot and humid. Please don't blame silver or a manufacture of silver jewelry. The green is actually caused by oxidation, and all silver will oxidize (it's also what gives silver a tarnished look). There are some cheap jewelry items that cause the same effect. Most of them contain nickel. It's not poisonous in small quantities but it can provoke a reaction in people allergic to nickel. This "green finger effect" may also be an allergic reaction to alloy elements in sterling silver or gold. In some cases, the alloys, used to make jewelry more durable, may react with your body chemistry, causing a harmless green or black discoloration on the skin, which can be easily removed with soap and water. For this reason, most retail silver jewelry and white gold jewelry is plated with rhodium, which serves as a defensive layer and prevents this reaction from happening to anyone with allergy. Another reason may be lotions, soap or chemicals that come into contact with your skin on an everyday basis.
No.
Gold-tone over base metal is not the same as gold. Silver-tone over base metal is not the same thing as silver. Many base metals are used to make jewelry, and they are often coated with paint to make it look like gold or silver, but once the paint wears off, the metal can react with the skin and turn it green. This is especially true of jewelry that is made of copper and then coated with paint. Copper reacts to the sweat in a person's skin, and turns green. Gold-filled and gold-plated jewelry may also have certain base metals that react with a person's skin. The same is true of silver-plated and silver-filled. Sterling silver, Bali silver and such are not reactive and should not turn the skin green. Gold should not turn the skin green. Electroplate is another way of fusing gold or silver to base metal, and it is very durable, but if the plating ever cracks, the base metal could be reactive with the skin. The way to avoid purchasing something that will turn your skin green is to check for the tiny stamp imprinted on gold (it will tell how many carats of gold the jewelry is made of) and sterling silver (it will say sterling, and perhaps be accompanied by some numbers).
