The easiest way is to look at the underside of the stone and see if it looks smooth or rough in texture. If they have been sealed then the surface will have a smooth texture. 

Another way to tell is by placing a drop of water on top and seeing if it beads up or spreads out flat. If there has been no sealant applied, then the water should spread across the countertop evenly.

Q: How do I know if my white quartz has been treated with a clear coat?
