I also love the top granite but there is a fairly strong vein of pink hues running through it. It is perfect for us, and we are not pink people, but I am thinking of when we go to sell the house down the road. I feel the beauty of the piece as a whole will win the day, but you know how some people are about certain colors. It will take almost 2 slabs to do the 8x4 island and the surrounding countertops so that adds up to quite a statement.
We were going to do just the island in the exotic granite but found that the only thing that would work on the perimeter countertops was black and we definitely do not want black. Other colors were either too busy or too expensive. Choosing black granite would make me a slave to every bread crumb and speck of dust. We have it on two bathroom sink areas and we hate it. I am too old and too lazy to wipe down that much space every hour.
get the one you love, don't worry I'm sure it will be a selling feature that moves the sale of your home along quickly.
