gold jewelry and iron?

MHM is right. I will add though, that cosmetics and the pH level of perspiration aren't the only culprits. Moisturizing soaps and body moisterizers can cause the same reaction. I briefly used a moisturizer that caused green/black marking with every piece of jewelry it came in contact with. Needless to say, I got rid of that moisturizer straight away.

As for alloys as the culprit:

White gold is known to cause more reaction due to the use of nickel to yield the white color. White gold which uses Palladium, as opposed to nickel causes fewer reactions. And, the copper used in yellow gold can cause discoloration.

So, if you're wearing 18k & 24k then it's probably not the alloys, but the moisturizer or maybe even the perfume you might be wearing. It is recommended that jewelry should be the last thing you put on, after your moisturizer, clothing, and perfume. This will limit possible chemical interaction with your beauty products.

Here's a link that discusses the issue, and provides other links for additional details.

Good luck!

It has to do along with your physique's pH point! i do no longer think of it potential you have an iron deficiency regardless of the undeniable fact that it somewhat is conceivable. it is often times a symptom, yet i think of you would be feeling different warning signs as properly. it would additionally propose that it is not 24-karat gold yet once you're confident that it somewhat is, you are able to have it wiped clean.

rubbing a gold ring across my face leaves a greenish grey stripe, and i have low iron levels. but most info on the net seems to say it is either a reaction to sweat etc, or caused by contact with cosmetics.
