Brecciated Jasper, but Heartstone works pretty well, too.
I'd have to guess Great Lakes region or West coast.

Interesting guess, nichwhitt, it does look like it. But many times color is the most unreliable of traits to go by. The angular white quartz chunks are the breccia, and they have been cemented in the red Jasper (silica) matrix. That's my guess anyhow. So, if it were Cinnabar, it would be "Quartz in Cinnabar" and not "Cinnabar in Quartz".  Cinnabar, is a 2-2.5 on MOHS hardness scale. One reason I am guessing that this a red Jasper matrix is that the stone has obviously been water-worn or rounded and smoothed like many of the stones you find. I'm guessing that it is unlikely that Cinnabar would hold together to be polished in this way seeing as how soft it is. Although Cinnabar is still presently being formed and deposited from the hot waters of Sulphur Bank Mine in California. Specific Gravity of Cinnabar is also very heavy, 8.1. Scratch test anyone?  |

Brecciated Jasper is probably correct but it also looks like some Arizona fire agate that I have.
