There are many examples on houzz of contrasting counters for perimeter and island. For example butcher block on island and stone on perimeter or a solid color on one and something with movement on another. I would only mix two stones if one had movement and one was fairly solid. The stainless on perimeter and something else on island sounds good to me. Here is a pic of stainless counters with what looks like a stone breakfast bar. (I hope I understood your question right). http://houzz.com/photos/3137660

Also take a look at Room and Board....they have several tables with different wood finishes or wood/steel/metal bases and a good selection of various tabletop materials. Also if you prefer a wood table, an area rug underneath the table could also help to break up all of the wood too.

This is a kitchen going into a dog kennel building so I'm not too worried about resale. My dogs are raw fed and so I spend quite a bit of time prepping food, washing bowls, etc. I'm only 5'6" but I've been doing these tasks in our house... in our current kitchen which has counters at 35 1/2"... and my back is constantly killing me after I get done. I've purchased a long stainless steel counter top for the kennel (with built in sinks) but plan on the cabinets underneath being custom built. Just can't figure out what height. I was wondering... if I'm sitting at a table (which is comfortable for me to work at for hours on end) and I measure where the table top "hits" on my body and then stand and measure the distance to the floor, it's about 41". I'm wondering if that is an indication as to where my counters in the kennel should be! Seems awfully high! I may need to take the counter top I've bought and put it on some saw horses and varying heights and work on it to see what is best before I make the call!

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.
