I loved this so much that I bought two. I always get compliments on it, and I've worn them daily and they haven't tarnished/changed colour. However - they tend to unscrew on their own and fall off. This happened quite a few times until the bar fell off/separated from the head [that was screwed in]. This happened with the first one and I repurchased it and it happened again to the second one a few days ago. I am really considering if I should buy another as this is one of my daily jewelry pieces but I am unsure if I should. Overall I gave it 4 stars simply because of how beautiful it is and that fact that they don't tarnish with heavy wear.
