3.0 I like Helzberg's, but I don't love that they do not guarantee their products for just about any length of your time Except if you spend more for the lifetime guarantee. I bought my granddaughter an "H" necklace & lower than 3 months later on, the chain clasp broke. https://brooksxokap.suomiblog.com/the-definitive-guide-to-kendra-scott-cross-necklaces-47522506
