Blue Nile has been around a long time. Their products are good and their customer service is great. I've purchased a lot of gemstone earrings from them, after reading many positive reviews from TPFers, and they've all been top-notch. Years go I did return a bracelet to them that I didn't like and thought was not up to their quality standards and they were great about it. I've never had reservations about ordering from them and in fact prefer them over other online jewelry stores.
