I bought this for mom for Mothers Day and she loves it. I looked around for awhile wanting to buy a solid gold chain but those prices while worth it just weren't in my budget. I don't feel like I've settled at all when I received this chain, it is beautiful. I almost didn't tell her that it was not pure gold, but I did, can't fib to momma ;) She agreed that it is beautiful and she wears it often. Its only been a short time so I can't attest to its longevity but I have confidence that it will look great for a long time, and that lifetime warranty covers it if it doesn't. Its a win all the way around. I bought the 2mm because she didn't want something too big, this size is perfect for her cross pendent or wearing alone.
