Black Galaxy Enhancer Description

I recently put a deposit on black galaxy Granite (http://tanbrown.org) for my kitchen.
When I looked at the slab I saw a black dried substance on the side of the slab. I was told it was an enhancer. I was also told that all of the Granite (http://tanbrown.org) is enhanced anymore and (http://maplered.com) it does not wear off. Is this true? They said that if another company is saying that their Granite (http://tanbrown.org) is not enhanced, they are lying. Is this true?
Should I get my deposit back? They seemed to be very knowledgeable and (http://maplered.com) have been in business for 30 years.
