What stone is stronger than quartz?

In terms of everyday household use, granite is the clear winner because of its resistance to damage from everyday kitchen activities. While both stone materials are stain and scratch-resistant, only granite is heat resistant.

Is granite The strongest stone?

Granite is one of the hardest substances in the world. The only material that is harder than granite is a diamond. The hardness of granite makes it durable. Unlike other stone types, granite won’t crumble or break over time.
