This is a good weight and size for necklace extenders, which is what I purchased it for. I haven't used it long enough to know how well it will wear with time, but the color will work well with rose gold or copper chain and components. Hopefully a similar size and style of curb chain will start to be made in rose gold filled soon or higher end pieces.
It's a very decent but generic chain. I will probably use it for extenders. I prefer a more decorative chain, like the peanut or ladder ones, for most necklaces of this size.
