Nope not against the law. That's like saying the gold you base the currency off is not allowed to be manipulated. Manipulating or defacing currency for means of trade or illegal activity is against the law.
You are most likely allergic to Nickel. My mother has the same allergy. Nickel is perfectly safe to those without the allergy. Ear rings and other jewelry made from Nickel are an issue for those that have the allergy. I have a nickel ring from 1975 that I had worn for 25 years before I lost it. I made it in grade school with a torch and punches. What ever you do. Do not get a piercing and then use a nickel plated ear ring. You will have major issues.
