The diamonds are very pretty. I am beyond furious that within 2 weeks, the back has come off and nowhere does it list the size of the screwback to buy a replacement. I check them every morning so I know that it wasn’t the fault of my own. These are not cheap. The quality should be for the entire earring not just the diamond and post. Thank heavens the post stayed in her ear! I now have beautiful earrings that I bought my daughter for Christmas that she can no wear and that hurts my heart. Does anyone know how I can get a replacement back?
