Hi Blackie,
Sorry it took so long to get back to you. The travertine is color is called Walnut. You might find a different name from a different supplier, so it would probably be best to check them out in person. Here's a link with a picture of the color.
Walnut We didn't buy from this company and actually got them at Home Depot. We looked through a bunch of boxes and selected the best looking ones. My wife wanted a lot of color/character.
Kman was correct as far as the edge being called pencils. I didn't use that though. What I ended up doing was picking up this...

and cutting them.
You think after 4 months I could have waited another couple of weeks, but I was unable to find the pencils without ordering them, and I wanted to get this done.
