Earrings in silver 925%, stud with square black crystal
These studs / ear studs are made entirely of 925 sterling silver, the very best quality silver and have a square swarovski crystal. This means that the silver content in the jewelry is very high, so that they also contain no trace of nickel. So for those with a nickel allergy, there is no problem at Evy's Secrets. The crystal is available in different diameters, 3mm-4mm-5mm-6mm-7mm-8mm.
