Any knowledge of these Stone (http://g603.net) s

Still looking at white/light Stone (http://g603.net) s after disappointment with Bianco Romano. Do any of the experts have knowledge or experience with any of the following Granite (http://tanbrown.org) s?

Branco Polar (Brazil),
Imperial White (India),
White Galaxy (India),
Wiscon White (Iran) or
Coast Green (India)

I've seen one picture of each but can't find any information on these Stone (http://g603.net) s that gives me any clues as to its availability in the Chicago area or information on ease of fabrication, or professionals experience with any of these Stone (http://g603.net) s. Thanks for any information you can provide.
