I love this silverware. I've had it for almost a year, and it is still gorgeous. I regularly use the dishwasher to clean them, and so far no issues. Sometimes there are dark water/tarnish spots, but they are still beautiful, and usually rubbing them with my finger is enough to get the spots out. When we moved, we didn't unpack everything right away, and I was using one of these spoons to cook everything. That spoon did get a little discolored from the heat, so I would be careful about that. It turned more of a lighter gold color, rather than the deeper copper, but it isn't super noticeable. With the hammered texture, minor discolorations don't take away from the beauty of this silverware.
