How about the red granites like Iron Red?

Any of the true granites are very hard and durable, with very little care (no sealing).

The stone industry has rather broad definitions of 'granite' that have little real connection to the actual material's geologic classification.

I don't know technically speaking, but I have sapphire blue and I think it is a dream to live with. (except for not being able to see the dirt, so I am constantly rubbing my hands over it to see who left what when they ate and did not bother to clean up:)

Shelaaus,
Could you post pictures of your sapphire blue? Its on my list to see.

Without doing any back referencing to prove it, when we were shopping for granite, I thought I read that Emerald Pearl was pretty tough.

Our Azul Do Mar is bullet proof. Even though it is sold as granite, it is quartzite and harder than granite because it is mostly composed of quartz. It is low porosity and we haven't had any staining even though it isn't sealed and people in my house don't always spot and clean up spills right away and we cook a lot. The only issue with it is that, like most blue granites, it was expensive though not as expensive as Azul Macubas which is also quartzite.

We tested samples of Verde Sao Francisco and Costa Esmerelda and both did fine with staining and kitchen acids (vinegar, wine, lemons).

I have Costa Esmeralda and it has been bullet proof for us.We sealed it and it does not stain. DS likes to bang his fork on it and there are no chips!

I am currently shopping for granite. Actually just researching/window shopping for now as it will be spring before we can do it. Anyhow, I brought home a sample of Verde Butterfly I liked and put it to the test. I left balsamic vinegar, red wine, lemon juice and olive oil on it overnight and there were no stains or etching. I don't think the sample was sealed either.
