3.0 I like Helzberg's, but I do not like that they do not warranty their products for just about any length of your time Except if you shell out added for your lifetime warranty. I bought my granddaughter an "H" necklace & under three months later, the chain clasp broke. https://delta-8-carts51310.wikilentillas.com/1136935/charm_pandora_jewelry_can_be_fun_for_anyone
