Platinum
11 Answers
I always thought platinum was a very stable metal and didn't react to other substances on the whole.
For some strange reason my finger has become discoloured underneath my platinum rings. I can think of nothing out of the ordinary I have handled today and I have never had a problem before.
Any ideas?

Had your hands near any acids, even lemon juice (citric acid), as that can cause the oxidation process to PtO2 (known as "Adams catalyst").
Often colouring in gold is from the other chemicals in the alloy (lower K (caret) being higher risk)......your platinum bands aren't a PT alloy are they as that is an alternative....

I handle citric and acetic acid on a regular basis yet I've never encountered discolouration like this before.
The only 'unusual' item I've handled today is a pomegranate, not that I recall any issues in the past.
My rings are old and well worn, I've never experienced such a reaction before.
Perhaps I just need a wash ;-)
