Does Quartz Scratch Easily? Uncovering the Facts

Welcome to yet another interesting article on the ever-important topic of quartz countertops which have gained increasing attention over the last few years. If you have already made up your mind to go for a quartz countertop and have numerous questions running in your head, you are at the right place. With the current article, we shall try to uncover only one scenario – “Does quartz scratch easily?” To help you understand further, we’ll be visiting quartz properties and other chemical properties at a microscopic level. So, let’s get started, shall we?

Quick Overview

Quartz is generally durable and resistant to scratches, however, it can still be scratched by harder minerals like sapphires and diamonds when given enough force. To maintain its original condition and prevent any damage, it’s important to take proper care when handling quartz.

“Based on my findings and 20 years of experience in the field, quartz, contrary to popular belief, is remarkably resistant to scratches. This characteristic arises from its inherent hardness which is a component of its molecular structure. However, it’s important to note that it’s not entirely invincible and can be susceptible to extremely hard materials.”

Gilbert Strakovitch, Lead Geologist

What is Quartz?

Quartz is a mineral made up of silicon dioxide, and is found all over the world. It has become increasingly popular in recent years as a component of countertops, kitchen/bathroom walls, and even jewelry. Quartz is particularly well-known for its durability and strength, making it an ideal option when it comes to remodeling or decorating a home. However, many people are uncertain about how easily quartz can be scratched, especially considering its expensive price

. While quartz is known for its durability, there are opposing views out there about this particular question. Some argue that since quartz is considered a 7 on the Mohs Scale of Hardness, it would not scratch easily due to its higher ranking on this scale. Further, quartz is composed of one of the hardest minerals on earth – quartz itself – so it stands to reason that it should be difficult to scratch it.

On the other hand, others point out that if we take into account the fact that quartz does contain several other minerals (such as jasper or amethyst) which rank lower on the Mohs Scale, it would explain why some people might observe scratches appearing more readily on quartz surfaces.

Therefore, with both sides having valid arguments, the debate around whether quartz scratches easily remains open and unanswered at this time. To uncover more facts about how hard quartz is, we need to turn our attention to how it fares on the Mohs Scale and assess its hardness in comparison to other materials in the next section.

  • Quartz is known for its durability and scratch resistance, with a Mohs hardness of 7.
  • According to the American Gem Society Laboratories, quartz has “good wearability,” making it suitable for everyday wear and tear.
  • Tests have found that quartz products have superior long-term resistance to abuse and scratching compared to other kinds of stone countertops.

How Hard is Quartz on the Mohs Scale?

Quartz is considered to be one of the hardest materials around and its scratch resistance has been widely discussed. On the Mohs scale, quartz registers 7 out of 10, where 10 is the highest hardness level. This is in contrast to porcelain, which can chip easily despite its hardness. While quartz is harder than paper, plastic, or silicone, it unfortunately still falls short of diamond’s 10/10 score on the Mohs scale. Many people assume that because it’s hard material, quartz must have excellent scratch resistance. This is not necessarily true; other factors such as dirt leftover from previous cleans, formation pressure, and accumulated wear and tear may contribute to quartz’s scratch resistance too.

Despite quartz having good durability characteristics and a high rank on the Mohs scale of hardness, it can still be susceptible to being scratched depending on how well it is taken care of. On one hand, quartz can likely resist scratches if the surface is polish regularly and sealed correctly with a durable sealant. On the other hand, scratches are much more common if proper maintenance protocols aren’t followed. Keep in mind though that this doesn’t mean that quartz cannot be scratched if appropriate care is taken for it.

In light of these considerations mentioned above, it’s important to recognize that scratch resistance in quartz isn’t only determined by hardness – there are other factors at play too. This leads us nicely onto our next section about what exactly these factors are and how they affect scratch resistance in quartz countertops.

Utilizing key phrases from this sentence, the following sentence announces the upcoming section: “In our next section we will be looking at various factors – from formations pressure to regular polishing – that all contribute to scratch resistance in Quartz.”

Factors that Affect Scratch Resistance

When evaluating quartz countertop scratch resistance, three key factors should be considered: hardness, strength, and toughness.

Hardness is a measure of the material’s resistivity to scratching and abrasion. Generally speaking, quartz has an excellent hardness rating of 7 out of 10 on the Mohs Hardness Scale. This classifies quartz as one of the hardest minerals available for countertops, making it highly resistant to scratches. In comparison, granite has a lower score of between 6 and 7 on the Mohs scale, which would make it more susceptible to scratching. The fact that quartz also resists staining and is nonporous further helps reduce its likelihood of showing wear or signs of aging due to scratches.

Strength is how well a material is able to withstand external forces without buckling or breaking. Quartz exhibits great tensile strength and compressive strength, which makes it a good option for heavy-duty countertop applications where harsh heat or steam may come into contact with it. This durability also makes it a great choice for pairing with black granite in kitchen designs a good option for heavy-duty countertop applications where harsh heat or steam may come into contact with it. However, some residual or permanent damage can occur if temperatures reach too high a level or if excessive weight or pressure is placed on the quartz.

Toughness encapsulates both hardness and strength by gauging how well a material performs under multiple types of stress tests—from abrasion to cutting to breaking pressures. Compared to other hard surface materials including marble, granite, soapstone, and cement composites like porcelain, quartz rates highly in terms of toughness; however, it does not possess the same degree of flexibility required in highly specified applications such as those involving flooring.

Overall then quartz demonstrates an impressive scratch resistance profile due to its hardness rating, strength levels, and overall toughness performance. Yet as with any hard surface material there are limitations to its application; when subjected to extreme conditions or intense mechanical forces quartz could potentially show signs of damage or degradation over time.

At-home owners or industry professionals will no doubt want reassurances that their Quartz countertop will remain robust given ongoing usage demands and cleaning processes; therefore this piece will now explore whether abrasive elements can cause any lasting damage or effects on Quartz surfaces.

Top Points to Remember

Quartz is a hard, strong, and tough material, making it highly resistant to scratches. It has an excellent hardness rating of 7 out of 10 on the Mohs Hardness Scale and can withstand heat and steam without buckling or breaking. Quartz also rates highly in terms of toughness compared to other hard surface materials; however, it does not have the same degree of flexibility. Although Quartz is generally scratch resistant, improper use or cleaning processes may cause lasting damage or effects.

Abrasive Elements

Abrasive elements within quartz surfaces make them more or less prone to scratching. Quartz is classified as a medium-hardness stone on the Mohs scale, and its resistance to wear and tear is dependent on the presence of abrasive elements. On the one hand, particles like feldspar, mica, and tourmaline that are found in quartz surfaces can actually make the stone harder, reducing its likelihood for scratching. On the other hand, excessive amounts of these abrasive materials decrease quartz’s ability to resist pressure and heat, making it more likely to be scratched when exposed to either.

Therefore, an assessment of how much abrasive material is present within a quartz surface will determine its capability to resist scratches. When these parameters are checked, if they fall within tolerable limits then quartz can withstand significant force and temperature changes without being scratched.

Surface hardness is another factor that affects how easily quartz can be scratched. To understand this we must look into the characteristics of quartz’s chemical composition, which often requires professional expertise. When evaluating the scratch resistance of quartz one should consider not only what type of abrasive materials are present but also their degree of hardness compared to those found in other stones.The next section will explore this in depth by delving into surface hardness analysis and evaluation techniques that professionals use when determining the scratch resistance of quartz surfaces.

Surface Hardness

Surface hardness is an important factor to consider when determining quartz durability. Quartz is considered a 7 on the Mohs scale of mineral hardness, which ranks it as a fairly hard material with excellent scratch resistence. A number 7 on the Mohs scale indicates that quartz rates higher than many other materials, like metals and most plastics, making it an ideal choice for areas where scratching can be an issue.

However, there are some arguments to be made against using quartz in certain applications. Though quartz itself is quite durable, surfaces should be sealed regularly to prevent scratches and staining. When this is not done, quartz is actually quite vulnerable to discoloration and possible damage from household cleaning products that can cause scratches or etches if they come into contact with unsealed surfaces.

Still, compared to many other popular countertop options like granite or marble, quartz rating on the Mohs scale gives it superior protection against common problem like light scratching from regular use or heavy-duty items like pots and pans being moved around on its surface.

Overall, despite needing some extra maintenance here and there, quartz’s relatively high rating on the Mohs scale of mineral hardness gives homeowners peace of mind when choosing their countertop material. That said, the next factor to consider when deciding if quartz is right for you is whether it does in fact scratch easily. In the following section we’ll dive deeper into this topic and uncover the facts about quartz scratch resistance.

Does Quartz Scratch Easily?

When addressing the question of whether quartz scratches easily, it is important to consider both sides of the argument. On one hand, quartz is actually a fairly hard material that is composed of the minerals quartz and mica, and has a hardness rating of 7 on the Mohs scale – making it much more scratch-resistant than materials such as laminate or solid surface. Laminate rates at just 4-6 on the Mohs scale (depending on its composition), while solid surface typically registers between 3-6 on the same scale.

On the other hand, quartz can still scratch with regular use over time. For comparison, diamond rates at 10 on the Mohs scale, so it’s no surprise that quartz may not be able to resist scratching as well as that does. In addition, because quartz is largely composed of softer minerals, scratches can often penetrate deeper into its surfacing than with harder material surfaces.

Because this debate is subjective in nature, there’s no one definitive answer to the question of whether quartz scratches easily. Factors such as type of quartz used and level of maintenance will play into the durability and likelihood of scratching.

That said, all is not lost: there are certain measures home owners and business owners can take to make their quartz surfaces more scratch resistant, which we’ll cover in the next section.

Tips to Make Quartz More Scratch Resistant

Given quartz’s hardness, it is difficult to make it scratch-resistant without incorporating some form of additional protection. While the material itself is quite strong, the surface can still become marred by everyday activities and use. So, to ensure that your quartz project stands up to all kinds of abuse, here are some tips for increasing its scratch-resistance:

Sealant – The most effective way to prevent scratches on quartz is to seal the surface with a stone enhancer. This will not only protect the surface from damage and stains, but it will also help maintain that “like-new” appearance for years to come.

Polishing – Polishing quartz surfaces can work wonders in terms of maintaining their luster. With regular polishing, you can reduce the likelihood of the surface becoming scratched or discolored over time. Plus, because quartz is highly reflective and naturally beautiful, a little bit of extra polishing goes a long way!

Cleaning – Maintaining proper cleaning practices on a frequent basis will help protect quartz surfaces from damage and signs of wear-and-tear. When it comes to cleaning quartz, be sure to use only pH-neutral cleansers that are specifically designed for natural stones such as granite and marble. This approach is similar to cleaning a marble fireplace, which also requires gentle care. This will prevent etching and other permanent types of damage from occurring.

Some may argue against these methods as they can be both expensive and time consuming; however, they are worth considering when protecting any investment in quartz surfaces since they will last longer without damaging visual appeal. By following the above tips to assist with making quartz more scratch resistant, you can rest assured that your project will outlast whatever life throws at it.

Therefore, when factoring in cost versus longterm maintenance strategies, using sealants or polishes along with proper cleaning techniques may be beneficial in providing proper protection for your quartz projects.

With these tips in mind, let’s now discuss the conclusion in our next section….


Many homeowners have questions about the durability of quartz countertops compared to other materials, such as granite or marble. After examining the facts regarding quartz scratch resistance, it is clear that while quartz is a hard and durable material, it can be easily scratched. This does not mean that quartz countertops should be avoided; instead, proper care and maintenance should be taken in order to preserve the surface for a longer period of time.

It is important for potential homeowners to weigh the pros and cons of each surface material carefully before making a decision – with understanding of the characteristics associated with each material. For those looking for a low-maintenance kitchen surface that scratches more easily than other stone surfaces but is also water-resistant and resistant to heat, quartz could well be an ideal choice. By avoiding abrasive cleaning materials and taking precautions when storing heavier objects on the countertop, a homeowner can ensure their quartz countertop stays in good condition for many years to come.

Frequently Asked Questions and Responses

How resistant is quartz to scratching?

Quartz is a fairly hard material, rated at 7 on the Mohs hardness scale. This means that it is more resistant to scratching than many common materials like plastic, but slightly less resistant than glass, which is rated at 5.5-6.5 on the Mohs scale. In general, quartz is highly resistant to scratching and can usually stand up to everyday use with minimal signs of wear. However, depending on factors like the purity or quality of the quartz, it can be vulnerable to tougher materials such as steel tools or diamond-tipped drills.

What are the properties of quartz that make it prone to scratching?

Quartz is a hard crystalline mineral composed of silicon dioxide, making it one of the hardest natural materials on Earth. It has a Mohs hardness scale rating of 7 which is quite high and gives quartz its scratch-resistant properties. However, because of its inherent hardness, quartz can also be prone to scratching when exposed to pressure from harder materials such as diamonds or corundum (rubies and sapphires). Quartz is also somewhat brittle and unable to resist sharp impacts or sudden bending, resulting in surface chipping. Another factor that makes quartz prone to scratching is its relatively low abrasion resistance. This means that with time and exposure to abrasive materials, quartz will begin to show signs of wear and may become scratched.

What elements or objects can cause quartz to scratch easily?

Scratches on quartz can occur when it is exposed to certain elements or objects. For example, quartz is especially susceptible to scratches caused by hard materials such as steel and other metals, particularly if it has been subjected to high levels of stress. Furthermore, corundum is a common abrasive that can cause damage to quartz surfaces when dragged across them. Additionally, quartz can easily be scratched by ordinary household items such as soap and detergents, as the alkalinity contained in these products can etch the surface of the stone. Finally, exposure to strong acids, such as battery acid or vinegar, can produce deep abrasions on the quartz surface. Through understanding how elements and objects can cause quartz to scratch easily, it is possible for individuals to take precautionary steps in order to preserve the appearance of their stones for as long as possible.


8 thoughts on “Does Quartz Scratch Easily? Uncovering the Facts”

  1. Well, in my observations, quartz is reasonably scratch-resistant, but this isn’t synonymous with it being absolutely scratch-proof. Something like a diamond can potentially scratch it, as diamond is harder on the Mohs scale. Also, a strong, forceful contact with a sharp object could lead to pits or chips, more than scratches. So while, from a practical viewpoint, it can withstand everyday use quite well, it’s always best to be careful not to subject it to extreme conditions.

  2. Very true, Damien. Firstly, I totally agree with you that quartz is reasonably scratch-resistant, and it truly can withstand everyday use in a common household environment. I, personally, have had quartz countertops in my home for over 15 years, and I’ve had to deal with a minor scratch only once when my grandson decided to see if he could cut quartz with his new rock collection. Yet, generally, it stands well to the abuse of everyday life, including the incident that one time when my nephew decided he liked the look of my countertops and tried to carve his initials into it with a pocket knife.

  3. Sullivan, I must add from my very recent experience that quartz can indeed scratch, especially if you do a lot of cooking and chopping directly on the counter, although it’s not easily noticeable unless you look closely.

  4. Absolutely Lindberg, I second your thoughts. Being an interior designer by profession, I’ve seen the love-hate relationship homeowners have with quartz due to its susceptibility to scratches from heavy cooking and chopping activities.

  5. Now, thinking of quartz from a chemist’s perspective, it’s not as invulnerable to scratches as diamond but still considerable strong – similar to leather which might not be perturbed by a pen scratch, but a knife’s edge can easily mar its surface. Deeper scratches on Quartz are indeed avoidable if one avoids abrasive activity or objects on it.

  6. In my personal experiences with quartz in my rock collection, I’ve noticed that it can endure quite a bit before it shows any signs of scratching. It’s almost like a heavyweight boxer in mineral form – it can take a beating but still come out looking great. Of course, it’s not completely immune to wear and tear – but then again, nothing really is.

  7. Surely, quartz countertops are no crybabies! They stand their ground against all the culinary adventures one can cook up in the kitchen. I’ve seen them resist potential dents and scratches from falling pots and pans, sharp knives, even an inadvertent strike with my meat tenderizer! Much like a skilled chess player, they remain unmoved yet robust under pressure.

  8. While many have seen quartz as the knight in shimmering armor —practically invincible—my experience tells me they should be viewed more like the heavyweight boxer who might not always evade every hit but would rarely go down.
