Unfortunately there are few standards in granite, and between marketing hype, slab yards, and fabricators, the consumer is left guessing. I might suggest starting with your local BBB or Angie's list, find a quality fabricator, and look at their offerings. Generally, the more movement or uniqueness in the stone, the more expensive. Sorry I don't have better news. Otherwise, hire a trusted designer partner with experience. They can save you a lot of headaches. Good luck!
