A water-based, low- or no-VOC sealer is typically a good choice for marble countertops. Choose a sealant that is certified safe for contact with food when applying to kitchen countertops. For high-traffic areas, look for formulas that have heat-resistant and acid-resistant features. While there are economical and convenient spray-on sealers, they don’t coat the surface as effectively as the ones you apply with a pad or brush. 

Granite is heavier than quartz, since it has a higher density. Quartz is made up of engineered stone, which is why it tends to weigh less than granite. Most granite countertops are ¾-inch thick and weigh about 13 pounds per square foot.

Unsealed granite is more susceptible to staining and other damage. Regularly sealing your granite countertops decreases the chances you’ll need to repair damaged countertops in the future. It also keeps it looking shiny rather than becoming dull over time. You can check whether your granite needs resealing by putting a few drops of water on the counter and waiting 15 minutes to see whether the water permeates the surface.

Onyx countertops have pros and cons. If you seal it properly and take care not to damage it, it can make a good countertop surface. However, it's more often used in bathrooms, where it’s less likely to sustain damage. Having an onyx kitchen countertop is possible, but you’ll need to take extra care not to burn, stain, or otherwise damage the material.
