3.0 I like Helzberg's, but I don't love that they do not guarantee their products for almost any length of your time Unless of course you pay back extra with the lifetime warranty. I purchased my granddaughter an "H" necklace & below 3 months later on, the chain clasp broke. https://hybridcloudstorage02345.fitnell.com/72665409/rumored-buzz-on-jewelry-don-roberto
