granite counter tops are the creme de la creme of kitchen spaces but adding matching knobs is a little much. At first glance, the knobs not yet attached to the cabinetry look like pretty chess pieces but fashioned to the woodwork they make for a busy and cluttered look. The only one I think that may bring an element of sophistication to a kitchen or bathroom are the dark slate colored knobs. But I still feel like less is more.
And who would have thought to chisel granite or stone to fit a light switch? Most granite has a mottled, colorful look and in my opinion only the purist color palette would work on a wall (unless your wall is granite too which would make for a blended look). Then again I don't wear animal print or plaid so maybe my tastes lean towards monochromatic schemes. In any case, I would leave the granite and stone to counter tops and quarries and keep it off the cabinets and walls.
