I am sorry to read about your chipped granite and I would contact the place of purchase to see if they can recommend a pro to take care of the chip.
BTW I have had pure white marble, granite, and concrete countertops and disliked each one for the time consuming constant maintenance requirements.
When I remodeled again I purchased all stainless steel countertops which look gorgeous, are indistructable, and I also had incorporated into my ss design a ss choppiong block, as well as a large long ss drain board tray which I place my Rubbermaid large dish rack on to dry items.
I purchased a large very deep one piece ss sink with apron on front which looks very chic.
I really like all ss the best, and it was money well spent.
The all ss matches my other ss items in the kitchen.
A fast wipe with a few drops of original clorox and water and then a final wipe with only water and a quick dry with a few bounty towels, and it looks clean and gorgeous all the time, with no irritating extensive maintenance requirements.
