REALLY cheap rings were (at one time) a thin gold wash over a base metal of brass. The gold wash would wear through almost at once, leaving the brass exposed. Brass leaves a trace of green color on the skin.
gold plate isn't durable at all it depends how you look after it as well..., as the sweat on your finger damages the ring removing the colour and leaving a horrible black or green finger ive had many gold plated rings myself !!
The value of gold plated rings depends on the price of gold and the rating of the gold karats at the time you are purchasing them. I would suggest comparing prices in several stores.
they are gold plated.
plated
it is not gold, it could be gold plated or brass
Gold curtain rings are quite common. Most are just colored gold but it is possible to find gold plated ones. Most hardware and Bathroom suppliers will have them in stock.
The gold plating could chip anytime, depending on what hit it or what the wearer hit with the rings.
Gold does not do that but copper does. Brass looks like gold and also makes the finger dark green. If that ring was given to you as a gold ring you got conned! there is alot of acid in your body when your finger turns green from your ring!
The rhodium plated don't turn you finger green, but your altificial white gold plated come back to yellow color. The people has to know yellow gold with rhodium it is fool... Because is soft and you has to mix with other precious metal to make jewelry; because in natural way don't good for jewelry !
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.
Sounds like it is a metal other than gold or silver. Might be gold or silver plate over a base metal. The gold or silver (if it was plated) could have worn down revealing the base metal, or you might just be having a reaction to whatever metal it is made of...usually will contain copper or nickel, which is why your finger is turning green.
You may want to have that ring checked by a reputable jeweler. It sounds like you have a copper ring plated in white gold and the plating has worn off the underside and is oxidizing from the moisture on your finger. White gold is Regular gold mixed with a white metal like nickel to change its color.
