The Science Behind Stone Countertops: What Makes Them So Durable?

Feb 17, 2025 | Premier Countertop Installation and Fabrication

Stone has been a symbol of luxury for centuries, but it’s only become accessible to homes of all budgets in the past few decades. Now, the modern kitchen countertop can withstand daily wear and tear with ease—and the reason these countertops hold up so well? It all comes down to science. Understanding the natural strength and makeup of stone can help you see why it’s such a smart investment for your home.

Granite: Formed Under Pressure

Granite is one of the most popular choices for countertops, and its durability is rooted in its geological formation. It is an igneous rock that forms under intense heat and pressure beneath the Earth’s surface. This process creates a dense, hard material composed primarily of quartz and feldspar.

The hardness of these minerals makes stone countertops highly resistant to scratches and everyday wear. Granite ranks 6-7 on the Mohs hardness scale, meaning it’s tougher than steel knives.

Additionally, natural stone can withstand high temperatures, making it a practical choice for kitchens. While no surface is completely immune to damage, stone countertops hold up better than many other materials when exposed to heat and sharp objects.

As a testament to their strength, the ancient pyramids of Giza and Mount Rushmore were constructed using granite.

Quartz: Engineered for Strength

Quartz is one of the toughest minerals on Earth—so tough that only a few materials like diamonds, sapphires, and topaz can easily scratch it. It is also the second most abundant mineral in the Earth’s crust. Quartz is one of the Earth’s most trusted minerals, valued for its strength and resilience in nature and your home.

Quartz countertops are made from engineered stone, combining natural quartz crystals with resins and pigments. This manufacturing process results in a non-porous surface that is highly resistant to stains, scratches, and bacteria.

Quartz is known for its uniform appearance and low maintenance requirements, making it an excellent choice for busy kitchens.

Natural Strengths and Sealing Protection

All natural stone countertops benefit from their inherent strength, but proper sealing further enhances their durability. Sealing creates a protective barrier that prevents liquids from penetrating the stone, reducing the risk of stains and bacterial growth.

Stone countertops are long-lasting due to their scientific composition and structural integrity. With proper care, they can last a lifetime, unlike laminate or wood. Their durability adds to your home’s value, making them a worthwhile investment.
