Dark stone coping

Hi,
I'm looking for some sample photos of pools with darker stone coping. Everything we've looked at so far is light gray, or too reddish, or has creme tones in it... Can anyone suggest and share some pics of a good darker stone for our pool?

Thanks, any idea what kind of stone that is?

I actually cant remember. I showed this picture to my PB and he knew exactly what it was. We think we want a dark stone similar to the picture. We are a ways out from picking stone but if I find out the name of the stone I will let you know. How close are you to making your coping selection?
