Not certain, but I think it's a good chance.
How is it possible that I could not know? Partly because it's under the surface. Partly because this marble style is not one I'm terribly familiar with. (<-- that is another clue )
I think I picked a good one. Plus, it's a great marble in its own right, if that's a clue.
I have to go to work soon, so don't think I'm ignoring or rejecting any answers. I should be back in 5 or 6 hours.
