More on counters

We can't seem to make up our minds. The sticker on the Monte Bello was high, so we continued our search and found it elsewhere with another fabricator at a much lower cost. It's still lovely but it's less green and more grey. And we still don't know what backsplash tile we'd use with it!

This new choice, Del Mare, is a green that looks really nice with the offwhite ("Drift") Boneyard Brick tile we like. So it is our current top contender. Concerns are that it might be a little dark or a little blue, but we love the veins, and it has yellow streaks that go well with the maple cabinets, too.

I am still going to look some into the whole granite/radon question and will post some links when I've read through more and my internet isn't being temperamental.

Assuming I get comfortable with the stone (since I can't seem to really like any more eco-friendly material for the kitchen, and even if I did, they cost a whole lot!), then I'd love feedback on this green! And the contrasting Monte Bello.

And the greyer, sublter, more neutral (but maybe ultimately too grey and too much like marble?)

Here's a reminder of what a board of that Boneyard Brick tile looked like with another green sample that would be similar to the Del Mare:
