I agree about the uniqueness, I think that's why it stood out! I too have pandora and apart from that I just wear my wedding and engagement ring. I have very sensitive skin so can't wear a lot of cheaper costume jewellery so I just don't bother buying much. I would wear this going out in the evening but I think it would look great with a white shirt or black top during the day too. I will have a look for solid rose gold pieces to see prices, I've never looked for rose gold before!
I only glance but basing just on what Pandora charges i would say significant. It is a nice piece and if you feel you'd get good use, a good addition.
