I used slate for mine. If you are looking at stone, slate is about as dead as you can get. The stuff is heavy though so you better have strong help when it's time to move it. Luckily I have a couple of rugged grandsons available.
When I built mine I was looking for a ruff hewn look. If I was going to build a new rack I'd use finished slate pieces for a more refined look. Check my system page for a pic.
