it is not gold, it could be gold plated or brass
gold ring does not turn black
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!
Gold will typically turn black when mixed with a different type of alloy. Bleach and chlorine can turn yellow gold black if it comes in contact with the gold.
My rings turn my skin black when I use a particular soap or hand sanitizer at work. When I use the soap at home, it doesn't cause a problem.
I have found that, any time gold turns my skin black/dark green, I am low in iron. I take one iron pill and the black/dark green goes away, until I become low again.
My bet is you have a cheap fiancee, and the ring's copper that was plated with a white metal.
Maybe because either it is not real silver (in which case the ring would start to turn a coppery colour after a while) or because you are allergic to the metal. Or it could be that it's too tight. My gold ring (I am not allergic to gold) is starting to leave a blue mark on my finger, but I think it's just because the ring is a bit too tight.
Your finger is inside the ring meaning she wants your finger to be inside her. Its meant to be a turn-on.
Platinum ring NEVER turns black. Only sliver rings turn black.
Means the ring is too big. Get it resized.
Do real gold turn black when you burn it
Not naturally it can't turn black.
