Swarovski 6 mm Neon Red Round Glass Pearl, truly elegant. The titanium stud earrings that are nickel free and truly hypoallergenic. Elegant simplicity in these earrings for women. Great for that sweetheart or friend with sensitive ears or a metal allergy. Glass pearl on a titanium post - no other metals. All metal components are made of titanium. For those ULTRA sensitive ears like mine.
