Quartz countertops have become incredibly popular in recent years as a durable, low-maintenance, and stylish option for kitchen and bathroom remodeling projects. But despite their name, quartz countertops are not actually made from natural stone. So are quartz countertops real stone? The short answer is no – quartz countertops are engineered stone, made from crushed quartz combined with resins and pigments. However, quartz countertops contain over 90% ground natural quartz, so they have some qualities of natural stone while offering additional benefits.
What is Quartz?
Quartz is a mineral found abundantly in nature. It is comprised of silicon and oxygen atoms and is the second most common mineral in the Earth’s continental crust, after feldspar. Natural quartz is very durable – significantly harder than granite. Quartz is found in different varietal names according to color and grain pattern:
- Rock crystal – clear and colorless
- Amethyst – purple variety
- Citrine – yellow variety
- Smoky quartz – brown variety
- Rose quartz – pink variety
While natural quartz can be used for countertops, it is extremely rare and expensive. Most quartz countertops consist of engineered stones made from crushed quartz.
How Are Quartz Countertops Made?
Quartz countertops are made by combining approximately 90% ground natural quartz aggregates with around 10% polyresin binders (polymer resins such as polyester). Pigments are added to the quartz and resin mixture to achieve the desired colors and patterns.
The quartz aggregates are ground into a fine powder before being combined with the resins and pigments. The mixture is compacted into slabs using a vacuum and vibration process that removes air pockets and compresses the material. This creates an extremely hard, non-porous, consistent surface. The slabs are then polished into the smooth, glossy finish of quartz countertops.
So while quartz countertops contain a high percentage of natural stone, they are not completely natural like granite or marble. The resin binds the crushed quartz into a durable, solid surface. The manufacturing process allows much more control and consistency over the final look and quality compared to natural stone.

The color options span neutral, earthy tones to bold and vivid hues. Many brands offer patterns that mimic exotic natural stones like marble or onyx. This wide spectrum allows homeowners to choose a quartz countertop color that fits their aesthetic vision.
Benefits of Quartz Countertops
There are many advantages that make quartz a highly desirable and popular choice for countertops:
Durability – Quartz rates 7 out of 10 on the Mohs hardness scale, harder than granite at 6 or marble at 3. This makes it very scratch and chip resistant. Quartz countertops do not need to be sealed.
Low Maintenance – Non-porous quartz resists stains, won’t harbor bacteria, and never needs to be sealed. Simple soap and water is all that is required to keep quartz sparkling.
Consistency – The manufacturing process removes natural stone’s variations. The entire quartz slab will have uniform coloring and patterns.
Heat Resistance – Quartz can withstand heat up to 212°F without damage. However, trivets are still recommended for very hot pans.
Non-Toxic – Quartz does not emit radon gas like some natural stones. It is VOC-free and food-safe.
Cost – More affordable than natural stone like marble or granite while offering extra durability. Specific price depends on brand.
Wide Range of Colors/Patterns – Manufacturing process allows colors and patterns not found in nature. Great for matching any design style.
Quartz combines many of the best attributes of natural stone and solid surfaces. When comparing countertop materials, quartz often comes out favorably in terms of appearance, durability, maintenance, and cost.
Quartz Countertops vs. Granite
Granite is a popular natural stone option. How does engineered quartz compare to traditional granite for countertops?
Appearance – Granite offers a completely unique look with natural variations. Quartz has more controlled, uniform patterns but unlimited colors.
Durability – Quartz is harder than granite on the Mohs scale. Less prone to scratches, chips or cracks.
Maintenance – Quartz never needs sealing, granite requires yearly sealing. Quartz resists stains.
Heat Tolerance – Granite can withstand higher heat. Quartz should have trivets for very hot pans.
Cost – Similar installed price range, but quartz provides more consistency. Granite has greater high-end cost.
Edges – Quartz has harder edges less prone to chipping. Granite can chip or crack over time.
Both offer natural beauty and quality. Overall quartz edges out granite in durability and maintenance while offering more colors. Granite excels in exotic high-end looks.
