Three.0 I like Helzberg's, but I don't love that they do not warranty their products for just about any length of time Except if you pay out more to the lifetime guarantee. I bought my granddaughter an "H" necklace & less than three months later on, the chain clasp broke. https://seersucker-summer-dress94829.articlesblogger.com/54578357/initial-necklaces-gold-options
