When I think of that name, I imagine a handsome black-haired boy with dark-brown mirrored eyes. Very cool name.

I met a little boy named Onyx several years ago, and it stuck with me as a really cool name. He was an unruly little hippy-style kiddo - totally adorable - but because I hadn't heard of it before (or since) he's my only association with the name. I would use it, but all the color names feel a bit limiting to me. I wonder what people with color names think of it...

I like Onyx and Ariadne better, but maybe Onyx Paxton with Ariadne? :-)

Wow, this is one that seems so obvious for a boy now that I see it, but I would never have thought about it before. I like it! The mix of vowels give it a cool, masculine flavor.

I disagree. A boy can pull it of extremely well

Best gemstone name for a boy. Dont like it on a girl whatsoever.

I love Onyx for a girl, or a black cat - either sex. A boy cat could pull it off better than a human boy, I think. :)

Is Onyx & Ariadne a good sibset? What about Paxton and Ariadne?

I can see this working for a girl also, maybe instead of Ebony.
