I love this ring except for the fact when I receive it the receipt that come with it which have a link for a website to the instruction , the link be incorrect . I also try to e-mail the contact e-mail multiple time with no response . the instruction below which someone so graciously post be correct , agree be very cryptic and be difficult to interpret , but I would still be try to put it back together without they . the first time I try to put it back together it take I upward of 2 hour to interpret the instruction and get it together . once you figure it out its not that bad . the groove that they talk about be located on the INSIDE of the band . good luck !
