My husband bought these for me a year ago as a birthday gift. I have worn them more than any other set of earrings I have (at least twice weekly) and I don't take any special care of them. Most of the time, they are tossed into a cup with a lot of other earrings. After a year, I've had no loose pieces, nothing came detached and no signs of wear or tarnishing.
  They are very delicate looking, not gaudy or overstated. In fact, they are so well suited for either dressy clothes or casual that I purchased the same ones in both red and pink for my other ensembles. I would say they are on a par with jewelry that I have purchased from Avon or JCPenney. They don't look "cheap" at all. Very tasteful. I highly recommend them for someone who wants to look classy and trendy but doesn't want their earrings to be noticed before they are.
