I agree with Alanis, that this sounds better for a girl. Apart from Jasper, which is one of my favourite names, I don't like hearing gemstone names used on boys. How can people call their daughters James, Michael, etc and then moan about Alanis using Onyx for a girl? Weird. I guess it's not the same people, but still, it is bizarre.
