Some people are allergic to metals. For the most part nickel is the culprit. According to Web MD some of the symptoms include itching, redness, rash, dry patches, and swelling of the skin. The symptoms from an allergic reaction typically appear between 6 to 24 hours after exposure.
A way to avoid a reaction to nickel is to ensure your jewelry is made of surgical-grade stainless steel, sterling silver, or copper. The Fused Glass earrings on my sites can be changed to surgical steel or sterling silver (small fee for silver) as requested. The fused glass pendants on my sites have bails which are free from nickel, lead and cadmium.
If you still have a concern I can coat the bail with allergy shield. In addition, I have a wide selection of bail-less pendants where a metal bail does not touch your skin. I can also change a pendant bail to silver (for an additional cost).
Allergic reaction to metals (e.g., nickel) is different than your skin changing colors. Maybe that’s a good article for next month’s edition of News from Elegant Fused Glass by Karen.
Please let me know if you have any questions.
