3.0 I like Helzberg's, but I don't like that they do not guarantee their products for virtually any length of your time unless you pay out more for that lifetime warranty. I purchased my granddaughter an "H" necklace & a lot less than 3 months later, the chain clasp broke. https://50s-summer-dress73762.vblogetin.com/37433814/the-basic-principles-of-jewelry-box
