How do I choose between G603, G654, and G682 for a kitchen countertop?

Start with the look you want and the light in the room. G603 is a light grey with a speckled grain, so it keeps a kitchen bright and hides crumbs well. G654 is a darker grey, often used where a stronger contrast is wanted. G682 is a warm, yellowish-beige tone that suits traditional or earthy palettes. All three are used for countertops and cut-to-size work, so the deciding factor is usually color and how the surface will be finished.

Do these granite codes tell me anything about quality or where the stone comes from?

No. The code identifies the variety, not the grade, the quarry, or the supplier. Two slabs both sold as G603 can differ in background tone, grain density, and how much they absorb, depending on the block they came from and how the slab was processed. That is why you should always ask for a current sample or photo of the actual lot before committing, rather than trusting the code alone.

How do I maintain a granite countertop made from one of these stones?

Day to day, wipe with a soft cloth and a pH-neutral cleaner; avoid acidic or ammonia-heavy products that can dull the surface over time. Granite is porous, so most countertops benefit from a penetrating sealer applied when water stops beading on the surface, typically every year or two in a busy kitchen. Wipe up oil, wine, and citrus spills promptly, and use a cutting board and trivet to reduce scratching and thermal shock.

What does G603, G654, or G682 look like after years of service?

A properly sealed and reasonably cared-for granite countertop tends to hold its appearance well. Light stones like G603 can show faint etching from acidic spills if they are left standing, and darker stones like G654 can show water spots or oil marks more readily if the sealer has worn thin. Honed or polished finishes may lose some gloss in the busiest zones, such as around the sink and prep area, but the stone itself does not wear through. Re-sealing and a mild polish usually bring the surface back.
