Granite Enhancer

We selected Giallo Antico granite for our new kitchen in a new home. My husband personally selected the slabs. When installed they look nothing like he selected. What he picked was a brilliant looking brown with gold, black and gray specks, with a hint of peach. What we are looking at now is a dull brown with black and gray specks and splotches of peach, NO GOLD.

 

The company has said if they put a chemical enhancer on the granite it will bring out the brilliance and the gold.

 

Is this true and will it be permanent?
