If You Sealed The Granite Will Make Darker

Pour a bit of water on the counter.
If you sealed the granite will make darker. If you need two or more slabs for a job you want to get them all from the same bundle preferrably or at least from the same lot or you risk the slabs simply not matching. Granite slabs come to the warehouse cut like a loaf of bread. Although you may find that many countertops do not require being sealed applying a sealer is common practice. A lot is made up of a bunch of bundles.
If you re going to place food or drinks on a granite table it s a good idea to seal it. Note the time that you placed the water on the counter and time the water to see how long it takes to absorb the granite will darken. As mentioned earlier dark stone is often more dense and won t need sealing but lighter color granites are often more porous and will definitely need to be sealed. Even a completely sealed granite countertop can stain if a spill is left to sit for long enough.
Test whether the granite needs sealing. And of course more lightly colored granite is more likely to show stains than darker colors so if you have a white or other pale colored granite countertop it s important to be extra vigilant. Perform a simple water test to see if your granite countertops need to be sealed. Lighter granite is more porous than darker and black is one the most dense stones out there.
But what s called the spill test is usually an even better way of determining this you just pour a little water on a test piece of granite and see if it changes color. 1 4 cup should be enough. Apple pie order gives some good advice but i would seal the samples first except the quartz or at least part of the sample so you can see the difference.
