3.0 I like Helzberg's, but I don't love that they don't guarantee their products for almost any length of your time Until you pay out more to the lifetime warranty. I bought my granddaughter an "H" necklace & a lot less than 3 months later on, the chain clasp broke. https://flenzy.store/stainless-steel-double-loops-cross-pendant-necklace-for-women/
